What am I?

So, recently I've been trying to find out what my sexuality is, I have always considered myself as simply bisexual but recently I've thought of being asexual since I do not feel the need for have sex with my boyfriend . But the thing is I enjoy fun time alone yet when it’s with him, irl or online (especially online) I always get a little repulsed or just don’t want to do it. I am bisexual but I’ve never experienced much with a woman, I don’t know if it would be the same with a woman? I really love my boyfriend and think that he is handsome but I am simply not attracted to him sexually. And it’s all men I think, I only have 2 ex but I never enjoyed sexual activities with them. I think it might be related to when I got groomed at 14 and by a 19 yo and he would force me to do sexual favors? My question is, am I asexual or am I something else? And what should I tell my boyfriend? I’ve told him I might be asexual but without much more details.
