Or do women just feel they hit the jackpot when they settle down with a guy who has never had a gf?

Actually no, most times this person will fuck your whole shit up because they have never been in an adult relationship so they dont have the necessary skills. Means they cut their teeth on you and grow of the trauma they inflict on you after you teach them and they move on.

The few, very few good eggs who come with good will cna easily work out. But more often than not, emotionally stunted males and inexperienced males are one in the same.

Its easier to be the beneficiary of the previous woman's years of hard work since more often than not, a lot of men associate u with their embarrassing struggles and start a "new slate", history and loyalty be damned.

Extremely common.
