I started doing this as a joke a lot, but it worked. Maybe that's what he's doing. Anyways, my girlfriend politely told me that she felt how you felt, and now I am more polite about asking.

She was very sweet when telling me that me pulling out my dick made her less likely to suck it.

It might be an awkward conversation, but I think relationships rely on communication. It might be weird for a bit, but yall will feel more comfortable with eachother after yall know how eachother feels.

To me, there's nothing wrong with letting him know where your guilt comes from. You're assuming he can't get it up and keep it up, but you might as well ask. There's a chance he has a specific turn on.

Hope this didn't come off as preachy. Good luck!
