Anal sex

I’ve been with my boyfriend for 3 years now and about a year ago he convinced me to try anal with him. I was a little reluctant at first but once I relaxed and we slowly kept trying more I found I started to enjoy it. The only problem is I get to a certain point where my mind takes over and I feel like it’s wrong and I should stop which my boyfriend hates and I feel bad about. He really enjoys it but I feel like sometimes he enjoys it so much more than vaginal sex which makes me feel kinda like normal sex just isn’t good enough anymore. I also don’t know if having anal sex regularly is okay? Google seems to make me feel like it’s dangerous and I shouldn’t do it. Any advice ?
