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.

I was wondering what exactly a cock ring does? And has it been known to be effective at what it's supposed to do? I have seen them in several places and have been too shy to ask exactly what their purpose is.

1) Could you give me some information about frigidity?

2) What is "sexual apathy" exactly?

What does one do when they are desensitized to their vibrator and need to check a consumer report before investing in a new one?

This might sound like a gross question, but I do need an answer! When my partner performs oral sex on me, I'm not sure if my vagina is moist because I'm wet or because I have vaginal discharge... which is what? Isn't it normal for a woman's vagina to be somewhat moist, and to have a little discharge? When a woman gets wet, how can she tell? And know the difference between that and discharge?

Also, my partner and I haven't tried intercourse yet (I am a virgin)... I've read your previous answer to a man who said his penis might be too big for his partner; I am worried that I'm too small/tight for my partner. It doesn't look easy for him to even enter, and I don't know how I can make my opening wider to accommodate him (how much foreplay, how long?). How much pain does the woman feel? Thanks a lot!!

1) I have never had sex, but I have tried now twice with my boyfriend, and it has been incredibly painful. It felt like there was a barrier inside me, and the second time I bled. I feel like I am relaxed, and my boyfriend is very gentle and slow, but it still really hurts — more than I think it should. I am able to use tampons — I'm not that small — but I don't know what the problem is. Is it supposed to hurt this much? Could there be something wrong?

2) I'm a virgin, and the first time my boyfriend inserted his fingers in my vagina, it hurt a lot, and I got sore down there. I didn't reach an orgasm, but faked it so he would stop. I didn't enjoy it at all and I was wondering... is this going to happen when I have sex? Is it going to be as disappointing?

Today my partner and I were having sex and he "released" himself inside me. After sex, he began using a dildo on me until I was satisfied. Well, after going in and out of me real hard and fast, a foam-like substance began to appear. The foam was exactly like hair mousse. I am not on any type of birth control (he has a vasectomy), and I was recently tested for STDs a couple of months ago and everything was fine. Could you please tell me what this may have been from!
