I thought I was proper ace, I'm grey ace at best but what that really translates to is low libido.
I'm happy to have vaginal sex with my wife, but tbh prefer fucking her tits, thighs, or recently since I found the right positioning, her belly/thigh/ pelvis crease. Let me tell you, that last one is fucking primo.
I think part of it is fear of pregnancy, whenever we do vaginal sex I have a small celebration when her period starts. I tried oral for her once and she told me to stop I was so bad. She's given me kral a few times and it was nice,but. I don't care about it.
