Is it normal or means something that your partner wants to have sex in the anus?

I'm 22 years old girl, the first time that i had sex for the fist time in my life was in the anus, because my boyfriend said i would'nt lost my virginity,and i didn't like it, but everytime that i had my period he asked for that kind of sex and sometimes i feel weird and think all kind of bad stuff about him.Is it normal or means something that your partner wants to have sex in the anus?
The request isn't that unusual... I have to admit I've made that request (and successfully) of a few of my girlfriends. It's just another aspect of sex that some guys prefer (many I know have tried it with their girlfriends) and really some women enjoy it also. You probably could enjoy it if you were open to it, but if you're not tell your boyfriend it's not an option. It's much easier on him also to know you'll never let him do it, rather than try to talk you into it all the time and be denied. There's no reason you should do something you don't want to, especially after you tried it once.
There is nothing wrong with him just based from this fact. He is just sexually curious and likes the variety. If he continues to pressure you into it after you told him no(if that's what you want to do) then dump him, because he probably won't be happy with strictly vaginal intercourse.
stay far from him. get a new bf.
If you don't enjoy it DON'T do it.
Plenty of males like it because it's tight and a lot of females do enjoy it. Other females flat out hate it and refuse.
It's not wrong that your partner requests it but it is wrong if he's pressuring you to do something you aren't comfortable with. No loving partner that respects you will ever make you do something that you dont want to do.
If you're thinking bad things about him because he's forcing your, then he's pretty much raping you even if you give in to him.
