You can ask me any questions you would like (although I cannot speak for all asexual people in the same way that you cannot speak for all heterosexual people).
He wanted to be sexually active as his friends were and he did not want to be different and was frustrated
It may be that he hasn't come to terms with it yet, or that he wants to fit in, or that he has never heard of asexuality. I didn't find out about asexuality until my mid 20s and I was confused before then. As soon as I discovered what it was then I was so relieved.
You say it has nothing to do with me . Tbh it has not felt like that .
He's not attracted to anybody, that's just the way he's built.
He's not going to change, it would be like trying to make a gay guy enjoy heterosexual sex or vice versa. I'm not getting at you but he's not a deviant or secretly gay, he's just not a fan of sex. Neither of you are wrong. Sex is important to you and that is perfectly fine. No sex is important to him and that is fine too.
You are going to have to decide if sex is something you can live without and tbh, it doesn't sound like you can. YOU ARE NOT WRONG FOR WANTING SEX AS PART OF A RELATIONSHIP but you are never going to find it as part of this relationship. If you're feeling this way after a few months then imagine after a few years, imagine after 50 years.
