ray32,
You said, “I did a bunch of kegels last night, maybe that was it, but I think it was more how horny she made me with such prolonged foreplay, and the surprise of having sex when she had earlier said she didn’t want to today. I felt so good though, we finished at the same time and hearing her moaning in my ear as I came was fantastic, put me in the best mood sex has ever done.”
It was definitely the latter, you were into her mentally and that’s why you were able to relax and enjoy her. The mind is a powerful tool, keep heading in the direction you’re going and you’ll be fine.
