Actually, most 2y/o's masturbate. Nearly all 10y/o boys masturbate, and are conscious of it giving them pleasure, or at least being comfortable having their hand there. In fact, a 10-13y/o boy does and thinks little (at least on the subconscious level) that doesn't have to do with his newfound toy. He may not even be aware that he is doing anything sexual when he does this, just that he has an 'itch' and doing this feels comfortable, all on the very edge of his awareness. Mothers of 10-13y/o's are constantly having to tell them to get their hands out of their pants (especially 'gifted' boys can do all they need to just in their pockets!)

Somewhere in this age range, their brain connects this with sexual emotions (usually around the time of their first orgasm, dry or not) and they will grow out of the public touching when they realize both that others can see it and that it's sexy (they get embarassed again).

There is nothing in this action to even suggest sexual abuse or contact of any kind. In fact, it makes it less likey, since if he had been sexualized (willingly or unwillingly), he would have connected the physical and emotional feelings already and would know tham to be private, and be embarassed to do it in front of someone in a non-sexual situation.

I suggest that you ignore his actions entirely, and simply engage him in whatever conversation is at hand. If (most likely) he is a 'normal' boy, his actions are part of growing up and his gazing at your package is nothing more than idile curiosity. If he is more sexually mature than other boys his age (unlikely, though still not confirmation of adult involvement, as a good number of boys make such leaps far earlier than the norm. It should be noted here that it is not unhealthy nor abnormal for a boy to mature faster even in this area all on his own. It is only unhealthy for him to be punished for his early maturity level that, while less mature than an adult's all boys go through at some point.) if indeed he is more mature through his own/friends' discoveries or through adult abuse, then let him escalte the relationship on his own when and if he is ready to make it f-ing obvious that he wants to. If he's been abused, he may see you as a person he can trust that he can tell. If he's horny and curious, he may have picked up on your BL curiosity and eventually try to seduce you (extreemly unlikely!!!). But in either case, you cannot initiate that conversation. Only he knows what he wants, if indeed he wants anything, and he will indicate it as clearly as he does with his same-age friends.
