Anal sex problem
my boyfriend lives far away so he comes over every like month or so and this one time we were in bed and i was on my period and he said we could try anal. I was up for trying new things but this was so weird, i couldn't decide if I liked it or not and it hurt really bad, anyways is it normal for it hurt? also it kinnda messed up my insides is that normal? and my boyfriend now really likes anal which is annoying because I do like it but its just painfull so I'm not sure what to say when he asks if we can do anal :/ help please?
