I think my dink is broken can someone tell me what’s wrong

I can only coom if my legs are straight, flexing my quads and calves.

So basically the only position I can coom in is lying flat on my back with girl riding.

I can’t coom doing doggy or missionary or any other position and it’s really annoying.

In fact, I don’t think I’ve EVER came while I’m standing position

Wut do?
