Plenty of men do date hot single mothers and plenty of them easily fvck them within the first 3 dates.
Ironically the women who tell guys they aren't interested in hookups or having sex early on are the ones whoa rr the easiest because it's done as a defensive mechanism to try and scare away guys who only want that because they know they can't control themselves.
Similar to a fat person not being able to control themselves around cookies or chips or cake or ice cream or pizza. They tell people they aren't eating any of that so don't bring it over. But yet if the person brings it over they end up binge eating it.
Same concept. The mind is strong but the body is weak...that tingling sensation overrides their logical thought process in the moment.
Then once it happens they are like "Oh well...it already happened so I guess it's OK to keep doing it".
If I had a dollar for every women who told me they weren't interested in having sex early on that I banged within 3 dates I'd have grocery money for a week.
