I have a question that I don't think you have addressed before (hope it's not too kinky). I am interested in learning the technique for doing a prostate massage. My partner enjoys being anally stimulated and I am sure this would be a "winner" for us. I just need to know the proper way to do it.

First, I'd like to thank you for this service! It's been so informative to read the advice you've given others. I'm a female grad student and have just gotten into a relationship for the first time. I have a few questions regarding oral sex: my boyfriend loves to suck my nipples and I feel great when he's doing it, but after a while, my nipples start to feel tender and actually hurt sometimes... is this normal? He's not rough when he's doing it, so I'm not sure why this happens.

Also, when my boyfriend "goes down" on me, I worry about what he thinks of my smell and taste. He says he likes it, but I can't be sure... is there some way of finding out if my scent is normal? Can he pass any infections (to my vagina) from his saliva? (He has had only 1 one-night stand affair and he used a condom that time).

Also, I masturbate him (I stroke his penis) until he "comes," but I'm afraid of tasting his "come." He hasn't asked me to, but I think he would like it if I did... how can I overcome this inhibition? Are there any risks for me? I appreciate any help/advice... Thanks a lot!

I am just curious about sex, and why is it such a turn on?? Is it the physical contact or sexual actions?? Or is it endorphins spreading through the body while it is happening??

I have started "cock-stuffing" in the past year or so. I use a glass thermometer and insert it into my urethra. I know that this is wildly dangerous — as the glass could break — but I thought it safer as it is manufactured very smoothly.

I know other men who use a variety of implements — pens, markers, tubes, etc., but I have only done it a few times — and it seems that the glass — while not safe as it could break — is safer as it must surely be smoother.

I use my own saliva as a lube — as I am not sure if a personal lubricant — i.e., Wet, KY jelly, or the like, is safe. Not that putting a piece of glass into your urethra is all that safe to start with.

My question — in the end — is personal lube okay to use? Is this a common fetish — I don't do it often — and it doesn't seem to affect me adversely afterwards.

Thank you for any light you can shed on this.

After you have sex, how long should you wait till you do it again?
