My first kiss with my partner, he asked "Can I kiss you?" and it was so hot! Because we had been hugging, holding hands, clear vibes of attraction going strong, and I'd told him BEFORE we met in person that I wanted to kiss him, and yet when we did meet I was excited and yet a bit nervous and awkward about who should make the first move and when.
So we got into my car after I picked him up from the airport, and he turned to me and said "May I kiss you?" and I gladly said "Yes PLEASE" and we kissed, and it was fantastic, and on the drive home we talked about what we wanted to do when we got there, and when we did, we ended up getting frisky VERY quickly. All with very enthusiastic consent. I loved it. And he's still my partner to this day!
