Trying to move on and date

I tried moving on and dating but I got grossed out after kissing this guy I've known for a while that I started talking to again. Guess he thought he was getting some. Ha ha not. Eww I feel gross just kissing him so imagine. I feel so down cause I know my recent ex is probably out with someone else meanwhile I'm being a loser. 😢😢😢 I'm so lame.
