I'd say about 2 weeks for me. Any longer than that, and it's a wet dream for me. I've done the deed just to avoid waking up with my drawers full of the stickyness a few times before.
I'm a bit embarrassed to ask this, but I have a basic sex ed question to ask.
Do you "need" to relieve yourself somehow every so often, or will your body absorb unused sperm?
I was always under the impression that the former statement was true, but just a few days ago I read somewhere that the body will absorb unused sperm. Is that true or BS?
