What kind of lube should I use when I cock-stuff?

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.


Why was my first time so painful?

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?


How can I reach orgasm with and without sex toys?

1) I'm not an inexperienced girl at masturbation. I've been doing it for a very long time, but actually only ever discovered what an orgasm was when I was 18 and got my first vibrator. This never bothered me because I wasn't sexually active then, but now it does. I realized I have NEVER been able to orgasm from physical touching or from just using fingers. I've always needed a vibrator of sorts and this is worrying me for future relationships and stuff with partners. How can I learn to orgasm from touch instead of vibration? I've tried before and have always just gotten frustrated or fallen asleep.

2) I've sorta been curious lately about what it feels like to do the big M using my fingers. I'm uncomfortable doing it though. I can't even use a tampon let alone do THAT with my fingers and I don't have anything that vibrates. What other options do I have?


Why is my boyfriend modifying his penis?

My boyfriend went down to the Village last night and came back with a pierced cock and I am completely grossed out by this. Moreover, he wants to have sex with it on, but it is of the type that would definitely scratch my insides up. What should I do? Also, he's thinking about getting his cock sliced into two parts. Alice, he's freaking out on me. I'm scared for him.
