I've always come to this site to either browse through others' problems and compare them to my own and because I've been sexually curious for as long as I can remember. Recently, a guy I've been friends with and I have started to "get to know each other." Last night, this question arose: How exactly do you "suck balls" and what are the benefits? I looked through everyone's questions, and I didn't see this one.

I am a twenty-three-year-old male who has a question about my scrotum. My scrotum seems to be tight up against my body, only sometimes does it drop a little lower. I thought that maybe my scrotum was just late in growing properly. Now I am not so sure. What should I do?

1) I had my first sexual experience on the weekend. Now I'm still bleeding. It's been about two days. Is this normal? How long does it last?

2) Recently, my boyfriend and I were fooling around and he was fingering me. He has really big hands with really long fingers and, for the first time, I felt a lot of pain followed by a lot of pleasure. After he was done, I checked my underwear and it was drenched in blood. I am assuming that my hymen was broken but I didn't think it was supposed to bleed for over two days and certainly not this much. Is this normal or is something else happening?

I took a piss and found a purple mark on my penis. I have taken a blood test, and the results are on the way to check for HIV, but I can't wait. What do you think it is? Did I just masturbate too hard? I did just yesterday.

My boyfriend has suggested "tit sex" as an alternative to intercourse, which we want to wait a while to go ahead and do. I want to know, what exactly is "tit sex" and how do you do it? Will it hurt?

First let me just say how much I love your website and your terrific advice — it has saved me from a lot of embarrassing questions. LOL.

You see I am interested in buying a sex toy, preferably a penis sleeve or masturbator (for me to masturbate with). I have recently asked my mom about this and she does seem like it is open for discussion. The only thing is, she wants to know if the use of sex toys such as these (that vibrate or not) are safe and if I can damage my penis somehow or if there are any risks using these kinds of devices. I don't think there are any risks except for allergic reactions or not enough use of lubrication. But I am not sure. So please, please Alice, answer my question.

I have a weird question. My boyfriend and I were talking and he told me that men's balls move on their own throughout the day. I did not believe him so he showed me. He got undressed and laid back on the bed and told me to lift his penis and watch real close. I did and unbelievably, his balls moved. It's like they vibrated kind of like a heart beat. It was so cool. What makes a man's balls move alone?

PLEASE, PLEASE, PLEASE answer this question for me. Are condoms you buy from machines in the bathroom safe? What I mean is, could they carry some sort of disease or STD or anything that can make me sick (I don't mean allergies)? And also, could you tell me if American condoms are better than other countries' condoms? I read that U.S. condoms are electronically tested for defects or diseases, but I was wondering if other countries like Europe or Thailand or whatever tested their condoms, too. If I was older, I would buy condoms from boxes, but until then, I am stuck buying them from bathroom machines.

I have a blood disorder (leiden factor V) which prevents me from talking any form of birth control with hormones in it. This is a problem as I am very paranoid about getting pregnant, I would like to have a child at some point, but not for five or six years. Condoms just seem to risky, and diaphragms and female condoms don't work well for me. So I'm not quite sure what to do. I am able to take the plan B pill, and wondered if I can just take it after having sex. Or if there are any other options out there I would love to know about them! Thank you!
