anal sex experiences?

Victoria
I've been dating my boyfriend for about 7 months and around month 4/5 he started to put his finger up my butt while having sex and I was kind of surprised at first and didn't really like it but I thought I would get used to the feeling but I never did so I told him I was uncomfortable when he did that and he respected where I was coming from. I was just wondering if any of you weren't really into butt stuff at first but then ended up liking it? Something about anal just grosses me out😖 but I'm also willing to try it ONE day, not any time soon though
