I don't know if my boyfriend likes my body.

I 18TF have been dating my boyfriend 18M for 4 months now. I recently asked him if he feels any attraction to my genitals (I'm pre-op and don't plan on getting bottom surgery any time soon). He responded that it doesn't bother him. That sometimes it's cute and hot to him and sometimes it's just there. I don't really know how to feel about this. He keeps telling me that our relationship isn't built on sex and that he loves me for me not my body but something about that feels weird to me. Im not really considering breaking up with him or anything he really is amazing but it feels a little weird to me. I don't know how to react the whole situation something just keeps scratching at me and I don't know what it is. Has anyone been through something similar? How has it felt for you?

Edit- Thanks for all the support. He really is a great guy and I understand now where he's coming from more. He is Bi/Pan definitely not asexual. We did talk but he's not always the best at articulating what he means (he's a little blunt) so I really appreciate all the help. And uhhh Fuck Chasers!!!

Update- I showed boyfriend the post and how supportive you all are and he finally realized how amazing of a boyfriend he is! Thank you all so much!
