None of the following is necessarily my opinion or my beliefs.

Can showing a boy love eventually turn him gay (or BL)?
Not sexual love. Say there is a boy about 6 or 7 who has a good relationship with an older male. The boy likes to sit on his older friend's lap and he likes to be held and stuff like that. Is it okay for the older male to allow this? What age is too old for a boy to do stuff like that? And can allowing this too much show the boy that it is okay to be that close to other males and when he grows up and hits puberty can that love turn erotic and make the boy gay? Should the boy eventually grow out of this stage? What do you do if he doesn't?

In contrast, is it when a boy doesn't get that sort of love from an older male taht he may turn gay? Or does anything turn anyone gay?
