i would rather have a small penis than an average (15cm x 13cm) penis as I currently do. it's so close to being an acceptable size (16.5cm x 14cm minimum) that it's almost like it's teasing me just by existing. at least if i had a super small penis i wouldn't wonder what if, or wish to myself "just one more inch!" like a kid trying to grab the cookie jar on the top shelf that's just out of reach.
there's literally no disadvantage to having an above average penis. if it's too long you can just use less of it.

Where do I go to meet and woo a girl who is into anime and video games and old movies other geeky hobbies?

I hear they are mostly in discord servers, but I have no idea what to do with that information. I've had poor luck finding them in public, unless they're autistic landwhales jingling with keychains and cat ears and rainbow hair at a coffee shop or something.

I have no illusions about the common body type or social skills. I've been a stable and entertaining boyfriend of multiple such types in the past but I made those connections through school, and I'm in the professional world now. And even if I went back to school they'd probably all be below my age range now.
