My asexuality is making me anxious in my relationship
(sorry if this post is bad, its my first one)
My boyfriend (16 m) and I (16 f) have been dating since we were roughly 13, but i have just come to terms with my asexuality (Im a sex repulsed asexual). I've known I was asexual since before we were even dating but it took me a while to accept it. this was because we are both in a christian community so it took me a while to de-brainwash myself and realize its okay to be LGBTQIA+. (for the sake of the post he is very christian and I am currently questioning religion but he is supportive)
The problem is that my boyfriend has no idea about my asexuality. It's making me anxious because I feel like I have to come out to him and because I think my asexuality will ruin our relationship. We are both very open about wanting a future together but part of me feels like we will never be happy together. I'm concerned that our relationship wont work because I'm a sex repulsed asexual.
I need advice on what to do. Because of his christianity, I don't know if he will understand or be supportive if i come out. unfortunately i also feel really guilty for not being honest about this with him. I really don't want to break up with him but I have trouble imagining this dynamic working out long term.
Any advice at all is appreciated.
