Weirded out by my thoughts.. Because im 23

So today I'm over a friends house for a BBQ .. Her fam of course is there and she has a nephew who had a bunch of his friends over. Mind you these boys had to be no older then 16 .. But my god I found myself checking one of them out .. He had pretty smile and gorgeous hazel eyes. I seriously couldn't keep from making eye contact with him.. I'm such a bad person smh but he really was a cutie !!!
