1) You've mentioned a lot in this service about a woman's menstrual cycle, and the risks involved with unprotected sex. Details that you have mentioned include, for example, the high risk of pregnancy (i.e., as a result of unprotected sex or failed contraception) during the "fertile period" of a woman's cycle. What I would like to know is: what (typically) are the various stages in the cycle (e.g., ovulation followed by menstruation, etc.), when do they typically occur in the cycle, and, most importantly, WHEN are the (typical, of course) fertile and infertile (minimum chance of pregnancy) parts of the cycle?

2) When calculating the length of your menstrual cycle, what is considered to be the actual first day of your cycle? Is it the first day there is "red" bleeding, or does it also include the first day or two of brown discharge?

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?
