Recently I have discovered if I change the settings on my shower head so the water pressure is harder and faster it works wonderfully as a tool for masturbation. My question is, is there any health risks for using water for self pleasure? My main concern is getting water in my vagina...could that cause issues? Thank you so much!

Recently there have been creams for women sold over-the-counter to improve sexual enjoyment for women. Are these lotions safe for women and the men who love them, and do they work? I am familiar with a particular lotion called "Viacreme."

You have a long section about female genital mutilation, but what are your views on male genital mutilation? Why make a distinction?

I'm a man and I'm engaged in a lot of sports and outdoor activities, but lately some of my friends said that biking could result in male infertility. Is this true? How? What are the other activities that could lead to male infertility? How can I stay healthy in terms of fertility?

My girlfriend and I like to drip hot candle wax on each other. Is that safe? Can there be any damage or anything? I wouldn't exactly want anything bad to happen to either of us down there... Thanks!

I'm a 19-year-old uncircumcised male. There was a group discussion about sex in my dorm, and people were describing how erect, an uncircumcised and circumcised penis should look alike, that the foreskin should pull back all the way. I had never thought anything of this before, but looking it up on the internet found that I have what I believe to be a frenulum breve, in that my foreskin retracts (unlike phimosis) but not all they way. Unfortunately, all of the information about this (as well as surgery info) is from the UK. I have searched the web for hours and couldn't find any information about this condition in the US. I was just hoping you might shed some light on my condition, as well as on a procedure called frenuloplasty.

When was the first dildo invented and what was it originally used for?

1) I am a male in his twenties, and I am considering circumcision. Is it safe to be circumcised at my age? And how many days do I need to recover?

2) I'm a guy who's considering being circumcised. What sort of health benefits are there to the procedure? Are there any drawbacks? Also, how much of the foreskin is removed? A little bit? Most of it? All of it, right down to the base of the head? Or what?

The service that you provide is very informative. Thank you for it. When I have sex with my girlfriend and I thrust my penis deep into her body, she says that she can feel it hit something hard inside her body. I can't feel it hit anything. She is very curious to know what it is that I am hitting. Could you shed some light on this issue?
