i didn't know you could get hemorrhoids from anal sex...
my bf and i have also started having anal sex, i haven't had any problems. also you will get accustomed to anal sex, for me it was an acquired taste, at first i didn't really like it, and now i do

all the best

LittleTex, you sound like an expert, could you give me some advice about cleaning up before and after? That's my only problem with anal sex. (sorry if i sound gross)
