Last night I was on a very successful first date. We talked for four hours in the restaurant, closing it down; then in the parking lot we hugged, I asked her if she'd like a kiss, and after the kiss she kept initiating, and it turned into a four-hour (11 to 3am) standing in a public parking lot make-out session. I had to rein it in in some ways; e.g. several times I needed to move her hands off my crotch.
The thing I think of as a failure was when (without genital contact) she was clearly enjoying herself, then said, "I'm going to come." What I should have done was moved to less interesting parts of her body, and said, "We need to slow down." But in the moment all I could think of was pulling away in a way that would make her feel like she'd suddenly turned disgusting, or continuing. I continued.
Because, deep down, I continually underestimate both my own attractiveness and some women's ability to orgasm, I was totally unprepared for that situation, and didn't see my options. It's always better to think things through beforehand, but frankly deep down I thought even if someone could come that easily, that it wouldn't apply with me.
In Christianity, we are all sinners. What I do now is decide how not to do it again, and confess it to God and trust in His grace; His grace is what makes Christianity unique.
I'm going to have to talk with her about limits before I see her again. Never thought I might need such a talk on the first date.
