ELI5: Kissing

Hello all, I've had a few dates with this dude; and I'm really attracted to him. We're going to meet again today; and it's very likely we're going to kiss.Trouble is, I have no idea what I'm doing. I'm scared I'm going to be bad at it. I was just gonna ask, "can I kiss you?" when the moment felt right. Is this a good plan?I'm probably over-thinking this, but I'd like to not seem so inexperienced at age 21.Does anyone have any tips on performing the actual action? Any tips to combat nervousness?It's the third date if that makes any difference.Thanks y'all.
