Could this guy be gay or is it just me?

This guy I met online is really nice, affectionate and claims that he's not looking for a hookup. I like his personality, but he seems a bit clingy even though I've only met him once. He texts me all the time and is really sweet otherwise. One thing that's bugging me is the fact that he has a bit of a gay lisp or higher pitched voice. I'm not sure if it's natural because there were very few instances when I heard him talk like normal for a few seconds before he goes back to the more feminine sounding voice. He also likes likes one direction and other bands girls mostly listen to. I know I may sound shallow, but I don't want to end up falling for someone who's gay and get my heart broken. Do you think he might be gay?
