1. No, being penetrated does not mean a guy should do it. You can be 100% straight (or whatever really) and enjoy anal, be a bottom... There are women who would gladly do a guy in the butt (with a strap-on), but it's a bit taboo and obviously, not every guy enjoys it, and not every woman would want to do it and social reaction is negative, so women don't really brag about that stuff. 2. That's not a question to me.
