Too self-conscious to make friends

My partner and I haven't been sexually intimate for a while but I've been very interested in hooking up with other people, especially because they have successfully formed intimate relationships with other people (we're poly). But whenever I imagine a scenario in which I'm meeting new people and getting to know them, I get too anxious wondering if I'll have to keep meeting people who don't understand my body and presentation as a trans man and don't respect my identity, and what if they think my stretch marks are gross or my shape is weird? What if my body hair confuses them? What if I'm not interesting? I'm lonely but I feel like I'm too self conscious to make friends.(USA)
