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.

In my shopping and looking for condoms, I NEVER come across a formal size chart. I have been told that I was "endowed" and that I need to look toward larger sized models, but all I ever see is "snug fit," "large," and "extra large," etc. How big is big? It would be most helpful if I knew what I was buying before I actually bought it. Do you know of the sizes of some popular condoms, or of a size chart resource?

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 recently been advised that my on-going migraines might be caused and/or increased by the use of contraceptives containing estrogen. To that end, I have been recommended to switch to a progesterone-only form of birth control. Which, in turn, basically means I get to choose between Implanon and Mirena (I really can't stand needles, so Depo is out for me!). I am only 23 years old, and have not yet started a family. I do want to have children someday, and am very enticed by the idea of Mirena lasting to the point when I might want to begin trying to get pregnant. However, all of the advertisements for Mirena state that ideal candidates have already had children.

Is Mirena still safe for use in women who have not yet given birth? If so are there any additional side effects to consider in this instance?
