Where is your favorite place to cum? Internal, outside, anal? What is the difference/why do you like this more?
My wife has never liked swallowing (or spitting), so that's generally out for me. We've been trying to have another kid for several years now, so I almost (maybe 95% of the time) cum inside her. Not only is it the best way to reach our goal lol, but it always sets off another orgasm for her. She likes to squeeze me inside her as I'm cumming; which of course feels fantastic. She's recently realized she loves anal, so that's on the table, so to speak, as well now. For me, it's a huge turn-on knowing my cum is inside her. Very caveman-ish. "This is my woman, this is mine."
With past girlfriends I REALLY loved having them swallow. It always felt like the cum was being pulled out of me rather than shooting it out. With them though, I never came inside of them. Even if they were on the pill, I'd always pull out at the last minute. Overall I'd have to say cumming inside is my favorite. Not only does it feel great but since my wife prefers it that way I get that added boost.
