IMV, the number in itself means little. I know a woman who when in her 20s slept with between 2 and three guys each week for about 3 years. One-night stands which sometimes became multi-night stands if she needed it and no other guy was available. I know a woman who when in her 20s wouldn't sleep with a guy until they had gone out for at least 6 weeks. Then in her 30s, her opinion became 'it's just sex' and so, if she liked the guy and got along with him well, she might have sex with him if things evolved that way, that time. I also know several, in 30s, 40s and 50s who regard sex between two consenting adults as a normal healthy thing. So, when I had no GF, two of them (separately) brought up the subject in terms of 'was I managing' or how was I managing (on my own)? They held the view "what are friends for if they can't help their friends in a time of need". I slept with each of them and two of them had slept with their girl friends when they were single. So the numbers mean little. Connection/reason for sex matters. I'd rather have sex with an experienced woman than a brand new inexperienced one.
Not that I recall, but I wouldn't have an answer, as I wasn't keeping score. I'd think, "Great! I bet she's really developed some skills!"
