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.

I have been on the Depo shot now for a year and I am supposed to have another shot September 6th, but my husband and I want to have another baby. How long should it take for me to get pregnant?

Can condoms be used for masturbation? Or is that a waste?

I have a latex sensitivity, but would like to perform safer oral sex. Are lubricants on non-latex condoms harmful if ingested? I can't seem to find non-latex, non-lubricated condoms anywhere.

I've seen you have given so much great advice in the past I was hoping you could give me some. I always use a condom when I have sex. I don't seem to last as long as I want to. I was thinking of trying one of those gels or creams that make you last longer. Is this stuff safe to use with a condom? Could it possibly break down the condom, causing it to fail? Thanks for any help, Alice.

I live in Prague, Czech Republic — Europe. Before asking any question, I should tell you that I really appreciate your service. As for my question, I would like to ask you about the most common reasons for condom failure as a contraceptive method. I suppose that the most frequent one is condom breakage. But what are the others? I am especially concerned about pregnancy risk implied by the accidental transfer of sperm in pre-cum to condom by fingers while putting it on.
