I have a bf but like to see who matches with me on dating sites - iin?

I am in a relationship with a lovely man. I do have some doubts about the long-term future but I am honestly in love and generally happy to be with him.

My question is..is it normal that sometimes I like to see who I match with on dating sites? I don't cheat on my man or even contact the matches I get, but I occasionally like to see who these sites will match me with. I could never tell my boyfriend so it feels like I am doing something wrong. What do you reckon, Internet?? Am I a weirdo or am I normal?
