I think this is all just very new to us, and we havent been with other people before we got together. He's really looking more for a connection than anything and I think he feels if he jumps into something with someone who already has someone else, he will get less of their attention or there will be less room for him. I will talk to him about it though.
He's kind of a hottie, so he should have no problem standing out among the rest.
But I have noticed the ratio seems off.
