My girlfriend claims to love giving me oral sex, but just when I’m about to orgasm, she stops and climbs on top of me. I want to please her too, but sometimes I just want to finish orally. How do I tell her this without seeming insensitive?

Let’s see. Maybe she just enjoys the journey, and not the destination, in which case you can sexily suggest you finish on her, rather than in her.

Or, and I prefer this scenario, she senses you’re close and wants to make sure she gets her shot, too.

Since it takes most girls more than two minutes to climax, she may be trying to prolong the process, so I think you should please her before she pleases you. Then, when she goes down on you, she may be more apt to allow you to finish. (It’s all about give and take here, buddy!)

If she still gets antsy, or just wants to turn oral into intercourse, try turning her around and giving it to her orally while she’s still giving it to you. (You get where I’m going without having to spell it out in a family newspaper, right?) This way, you’re pleasing each other at the same time and you still get to finish the way you want to!

About six months after breaking up with my boyfriend of two years, I was set up with someone. Our first date was great, and during our second we hooked up. Shortly after, though, I decided I just wasn’t ready to date yet. Problem is, he continues to text and e-mail me. He knew about my situation, so I was honest with him about why it wasn’t working, but he still won’t leave me alone. Now what?

You dated your ex for two years, so it’s going to take someone really special to sweep you off your feet and make you forget him — and that will happen.

Clearly, though, this guy didn’t do it for you. Whether it was him, or the fact that you’re still not over your ex, doesn’t even matter. Guy needs to move on. (At the end of the day, you tried. Good for you. Sucks for him.)

Next time he calls, have a guy friend answer. Stalker Boy should get the hint. If he still doesn’t stop, or just continues to text, two words: restraining order.

I want to further explore what turns me on sexually, but I don’t know where to start. Porn stores are vast and pricey, and the Internet only gives away so much in the download preview. Any suggestions on how to figure out what gets me tingly beyond the obvious?

A friend of mine told me about this Web site redtube.com. It’s sort of like YouTube, but adult content only. Videos are free, so it’s great for researching your trigger points. The site’s variety is amazing, with everything from girl-on-girl and guy-on-guy, to guys-on-girls, fetishes, groups and public encounters.

That said, it’s also mostly amateur, so don’t expect to find Tom Twelve-Inch and Dara Double Ds on there. Think of it as the free bread you get at a restaurant, holding you over until the main course arrives. (Of course, some of us can live on free bread alone, so if that suits you, well, you’re all set!)

Click around and and “take a bite” of everything, keeping a mental (and physical!) note of what turns you on — and off.

Then, once you’ve found what sates you, consider testing it out with your boyfriend or “special friend with benefits.”

To make it even more fun, head to a store like Babeland in SoHo, where a salesperson can recommend a toy or a more professional title based on your newly discovered taste. Have fun!
