For me it’s a jealousy thing, I can’t imagine being with someone who’s had several times more bodies than me. I’d be forever comparing myself to past lovers and feeling I’m just one in a string of many that will inevitably be replaced, almost like I’m their 4th dog or something. Since it’s rarer for me I also place a much higher significance on sexual encounters, and I don’t want to be with someone that wouldn’t treat me/it with the same respect and importance
It says a lot about their lifestyle and often times theirs don’t align with mine. If a girl has 15 bodies and I have 5 for example. I’d probably assume she likes to drink or party quite often, a lot of that also comes with other substance abuse be it nicotine or weed or whatever, and I personally don’t want to live 20 years longer than my partner and I also don’t want to deal with the cocktail of drugs a lot of these women are on . I just find a lot of them unproductive to put it nicely.
For me it’s a religious thing. God said not to have sex outside of marriage, and I am holding myself to that standard, so it’s definitely not an impossible thing to ask. Ofc at the end of the day it’s between her and God, but I’d rather be with someone who holds religion in a similar regard as I do
