Friendly
If you see someone eyeing your womb you're probably going to be weirded out by how friendly they're acting. You only let people who are really, really close to you look at your womb. So if this guy is acting that friendly he should have introduced himself first.
Imagine having someone you aren't friendly with trying to have a look at your womb. No thank you.
ぼく, もく
むつ
None
This friendly guy comes up to you and start to introduce himself, "ぼく-" but you stop him. He's been getting way too friendly with your womb and you don't want to hear who he is. He can ぼく at someone else, you're out.
Imagine only letting this guy start to introduce himself with ぼく before walking the heck outta there. Just because he was acting friendly doesn't mean he was actually your friend.
