I just left my third hookup with a top looking to bottom for a hung guy. He spent the whole time trying to take only the tip. The other two times, both guys had to tap out after a few minutes.
While I’ve only met three tops that bottomed, I’ve been hit up several times by total tops who’d said, “I’ll bottom for you if you’re hung.”
Why? If you don’t take dick on a regular basis, why not bottom for small guys.
