Perhaps this also makes people more likely to form bonds (including sexual ones) with any decent person they have in their lives, regardless of their gender.
I think that's true and can relate to that as a guy. I'd probably score low on abuse surveys as I was never hit not even spanked as a child and had rather decent parents, only somewhat emotionally neglected as my mother had severe depressive phases. I had a babysitter who was very motherly including cuddling and kissing me like a mother and I did form a very strong bond with her. I guess that would qualify as "grooming". Eventually we did some sexual stuff, which in itself didn't feel bad, on a physical level I really enjoyed it, but it was also always disgusting because it felt exactly like having passionate sex with a big sister or even mother.
I was surprised as well, but apparently it was already common knowledge that lesbians and bisexuals are higher teen pregnancy risks.
This harsh childhood effect maybe makes some sense to me. Perhaps this also makes people more likely to form bonds (including sexual ones) with any decent person they have in their lives, regardless of their gender.
