Why do I hate kissing?

STORY: A few months ago, a friend said that I should try making out with a guy at this party we were at. I wasn't 100% attracted to him, but I was a little tipsy and did it anyway. The whole time he was french kissing and I had my eyes open, disgusted, and not enjoying it at all. In the end... I felt taken advantage of because I kept telling him to stop and he wouldn't until the third time. It freaked me out. But now I have a boyfriend (who's a complete sweetheart) who I'm attracted to- but don't like kissing!? I can't tell if it's just the way he kisses or if it's because it reminds me of the other guy and how much I wanted it to be over. I still have my eyes open and just don't want to kiss him. I'm so confused and would really appreciate your advice on what to do. Thank you so much!
