1) Is having sex in the shower that is hot or in a hot tub safe? Someone told me the heat kills the sperm. I thought it sounds dumb but I was just wondering.

2) I have a question about sex in swimming pools and hot tubs. Will the chemicals deteriorate a condom? Also, can spermicide be used in water or will it be washed away? Please answer. Thank you.

1) Hi! I have a question about orgasms. I'm a female who has masturbated since her early teens and wonder if I've "overdone" it somewhat. I did it so frequently (sometimes every other day or so; sometimes I waited longer) that now that I'm in my early 20s, I find it harder to reach orgasm, and harder to have multiple orgasms (it used to come so easily to me). Have I "lost" that momentum? Can I regain it if, say, I stopped masturbating for several weeks or months?

Also, my partner stimulates me manually or with his tongue, and I haven't been able to "come" yet... is it because I've masturbated too much? Do women take longer to come? I think he gets bored doing it...

2) My boyfriend has trouble ejaculating, usually taking a long time. I was wondering if it could have to do with his constant masturbation during most of his young life. Could it be that the problem is me? Is there a possibility that we can improve the situation?

I enjoy performing cunnilingus on my girlfriend, and every so often, I get a sore throat. My question is, is it all right to perform cunnilingus on my girlfriend if I have a sore throat? Or is there a chance that whatever causing my throat discomfort could cause her trouble as well? Can the “giver” of oral sex pass along sore throat germs to the “receiver”?
