LOL some is personal. It depended -usually I don't know 5 or 6 -really depended on the individual person. We did not have intercourse for a number of reasons -sometimes it was everything but especially when I was still a virgin - I waited till age 24- what is "sexual " varies among people. I got serious with men who had similar values to me including that sex is part of being in love and committed only. And separately when I was around 20 the AIDS epidemic started spreading past the gay community so many were far more careful because of that. Plus I knew early on abortion likely wouldn't be for me so abstaining was a good way to avoid that potentially horrible choice. My personal values. When I was 42 and got married I'd had very few partners relatively speaking and for sure I made out with/hooked up with -many more than that -I started dating in 1979 or so.
I don't judge when single consenting adults have intercourse as strangers, first date, 10th date, committed, not committed -whatever!
For the OP it sounds like she's a healthy sexual person who prefers to wait. You sound fine with that. She sounds like a good and thoughtful and fun person!!
