I think the correct answer is the following: there is nothing wrong with that; especially if you are not a couple.

Yet, I get a feeling that men who do those things are players. I could be wrong, and I never said my opinion came from Mt. Sinai, it just gives me a certain impression.

I have also noticed certain women on different dating sites as I browsed through them. It is as if they are on every site out there. They look desperate, and turn me off as a guy.

I think it is best to be on one site. Two at the very most. If you are having no luck, then shut it down and move on.
