Longer answer: I get the sense that both of you still have a bit of adolescent edginess around sex. Prior to this awkward moment you'd exchanged "numbers," which to me—and this is just me—is kind of the stuff for dorm room confessionals, not 30something connections. All that is just infusing sex with more weight and meaning than it needs, to say nothing of a salt shake of shame, a bit the way younger people are with booze: it's "crazy" to go into a bar and order a beer when you're 21, even kind of "wrong," but just a thing you do at 30, and whether you've gone to 10 bars or 100 in those interim years doesn't really matter. Probably there were some nights when you drank too much, hopefully not too many. Shrug emoji.
Accept whatever you feel right now: a little jealous, a little aroused, a little curious, a little emasculated. That's all allowed. That will all pass. Recognizing feelings as they pass through you, without reacting too intensely, is kind of how you grow—and, alongside another, grow closer. Awkward moment for growth, for sure, but they don't call them growing pains for nothing. Hopefully you both get to a point, independent of each other, where that chapter doesn't induce a cringe. Life is both too short and too complex for something like this to be an emotional pebble in the shoe.
