Paralisis

Hi, so I was born with facial paralisis. It's a little invisible because I have some movements (for example I smile, but not openly neither evenly). The thing is I never had a relationship because I can't do the kiss movement. When it comes with people I really feel atraction I froze, I don't know how to say: I can't kiss, without breaking the moment. I'm not gonna lie, I fear rejection, I feel like nobody would like someone who can't kiss. It makes me sad, I don't like to talk about my condition so people just assume I can do things like kiss or blow balloons, and when it comes to that things I just can't. So I reject people and then I feel lonely. I wish I have more courage to just accept it. Sorry for the bad english, I'm spanish speaker.
