Wow, Todd, you have a lot of questions there. But your resident sexologist, Betty, is here to help.

Sometimes you will have sex with girls who can't make you cum. It could be you're just not turned on by your girlfriend. But ask yourself these questions. Can your girlfriend fuck for long periods of time? Or does she go for a short period of time and you're just not able to climax because you're not there? If you don't (or can't force yourself) cum, that could be the answer.

I do have to say that it's an impressive skill that you can just go and go like the Energizer Bunny. Many men can't accomplish that feat. Since you're not a fan of the quickie, you need to find a woman with the same sexual level that you have. Look for a girl who likes to go all night and/or have multiple rounds of sex (with breaks in between, of course).

If you're going to have one-night stands you need to tell women that's all there is—unless you're looking for a fuck buddy/friend with benefits. If they keep coming back for more it might be your prowess or the fact that you're concerned with them getting off too (which is a good thing). Also, I have to agree with you that sleeping with co-workers is never a good idea—there's always the gossip and awkwardness, if things go badly.

As for having sex with 2 chicks at once…this can be a good idea. Taking turns will allow you to go for extended periods of time and “get there”. Keep in mind threesomes can be tricky—they're about more than just fucking. If you and your girl decide to bring another woman into the bedroom, you will need to lay down some ground rules. Also, be sure to give your girlfriend lots of attention so she won't feel neglected.

To understand threesome etiquette, I would suggest you check out Adam & Eve's Nina Hartley's Guide to Threesomes; Two Girls & a Guy. This flick has professional porn stars Nicole Sheridan and Mika Tan (not just some cheesy 70s actors) and will make a good time better. Additionally, check out Access Instructional Media's My Three Way with Kelly Welles and Nicky Hunter to help make your fantasy a reality. You'll also want to get some sex toys so when one girl isn't servicing you, she can be pleasuring herself and staying wet. I suggest Nikki Tyler's Pleasure Vibe, the Little Lavender Clit Cuddler, or the Temptress Tiger .

Good luck!

Love, Betty

Dear Dan:

I don't run a dating service. But, I would suggest you try bars around colleges. If you'd like some tips on porn with smoking hot BBWs 18 to 20, I can help you with that.

Too many BBW movies feature women who aren't the 2 nd ‘B', but I can suggest a handful that do. Evil Angel's Phatty Girls #8 features some young, hot Black girls including Red, Diana and Flame. If you like cute, chubby Latin girls who look like they're from around the way, check out Totally Tasteless' Chubby Chicas #7 with Kasia and Karla Lane. For a flick with busty, young BBWs, check out Big Top's Boobville's Young and Plump—these girls are fresh, college girls including the stunning Devvyn Devine .

And if you'd like to see more titles that may titillate you, browse under the BBW genre.

Happy viewing!

Love, Betty

Dear Z,

I'm not entirely sure why you are asking this question. Are you planning a career in porn?

According to Dear Betty's doctor, 80 percent of the sexually active female population in their 20s and 30s has HPV (Human Pap Loma Virus). So, the same is probably true with porn stars. It usually clears after awhile and rarely becomes full-blown cervical cancer.

Many porn stars get tested for STDs at AIM Healthcare Foundation, which was started by former porn star Sharon Mitchell (who has admitted to having Herpes herself). According to Ms. Mitchell, about 66 percent of porn stars have Herpes. It is a requirement that porn stars provide proof that they have been tested for HIV and other diseases (and they are clean) on the set before they even begin filming. This has become more and more important since condoms are rarely used in movies (although you do see one every now and again). Being a porn star is like being a fireman—there are risks and you have to decide if it's worth it. Chlamydia and gonorrhea are common and they are easily treated so porn stars can return to the set within a few weeks, usually.

If you're not living the life of a porn star, be sure to have safe sex unless you and your partner have been tested for STDs. Our site has lots of condoms and lube to help you with that including Contempo Barebacks Condoms that are very thin, yet sensitive, and feel almost like you're wearing nothing. Flavored condoms like Trustex Vanilla-Flavored Condoms can help you mix things up—they also come in banana, strawberry and chocolate. As for lube… Slippery Kitty Lube is my favorite—it's water-based so it won't stain your sheets and/or feel too sticky. If you like your lube old school, pick up some Astroglide.

Hope this answers your question!

Love, Betty

Dear Perplexed,

Sometimes no matter the skill level, you can't make a man cum. He could be worried about his job or have his mind on something that delays his gratification. It happens to the best of us (not Dear Betty, of course). But if this type of situation happens to you frequently, you may need to go to BJ School to rethink your technique.

I would suggest putting 2 movies in your queue—Instructional Media's The Fine Art of Fellatio and How to Give a World Class Blowjob. The women in these movies are experts (and porn stars) so they know how to please a man orally. Your man will thank you. Literally. Additionally, rent a few flicks and watch your favorite porn stars' moves. In Northstar's Assocates' Deep Throat This #35, Amy Ried, Chelsie Rae, Sammy Cruz and Isabella give Peter North and his boys amazing BJs that lead to insane facials. Combat Zone's Destination Tonsils features Savannah Stern, Bree Olsen, Alexa Von Tess, and Nicky Nievez really going for it—they give award winning performances. And lastly, check out Madness Pictures' Cum Hungry Cocksuckers #6—starring Aaliyah Jolie, Britney Stevens, Amber Peach and Lyla Lei, this flick is all about the BJ.

And the last bit of homework I will give you is to practice, practice, practice. Buy a glass dildo or a realistic rubber one and bone up on your skills. Before you go for the real thing, practice on a inch ultra skin cock—it's ultra realistic and you might forget it's just a dildo. Glass dildos are also good—try the Glass Erotic Torpedo Glass Dildo—it's multi-colored and you can use it for your own amusement later.

I hope this helps. Good luck!

Love, Betty
