Maybe a little sex Advice??

Okay so a few things here.

To start out I’ve been to docs- they say I’m normal internally. So it’s nothing to do with that apparently.

Externally I’m very self conscious of my boobs - other things but that’s the main thing. I get really awkward during sex sometimes and I don’t get why. And I feel like it’s effecting my ability to orgasm. I don’t think I’ve ever had one. I’m just feeling a bit unsatisfied and not in the bedroom- the guy I’m with knows his stuff for sure 😩- but as a woman.

Why can’t I orgasm??? Everyone else gets to ☹️ it’s in me I feel it I really want to. I try not to overthink it in the bedroom but when my top is off ... it’s hard not to think about my chest. Any advice?
