Any position that you both like is OK and you as a couple will have to work out which is best for you two. Try all positions and do what gives you both
maximum pleasure. Of course you should vary position to keep variety in your sex life if possible and avoid monotony.
Anal sex or vaginal sex with man behind (both could be called doggy style) are both normal and can be pleasurable. You should do it any way you like. The
precaution for AIDS and other sexually transmitted infections are the same whether you have anal or vaginal intercourse. So either way, though you cannot
conceive after an anal intercourse, you can get infections and a condom must be used.
