Strange uncle?..!

This is so weird but I wanna see if anyone has or had the same problem?..

Ok my uncle lives 3 hours away from me and I don’t see him much but one time my dad my mom and I went to my cousins to meet up with my uncle my uncle had seen me walk in the door and he’s like “holy fuc*!! Your hot” at first I was like damn he must be blind cause I’m not but then the night continued and my parents went with my aunt for a walk and I was on my period so I didn’t want to do ofc I stayed but my uncle stayed too..I payed attention to my phone until he asked for my number I gave it cause I didn’t want to be mean lol and he took it and was like can’t wait to call. Again I brushed it off UNTIL we were talking and he said something like “have any boyfriends?” And I said “no not really into that” and he’s like “you know what sex is?” And I replied “yep” and he smiled and yeah just thought it was fuccing weird
