In my experience, kissing is an activity that some people are really into. Others, not so much.

The like or dislike is partly due to experience, imo. It takes a little while to develop skills and/or confidence in ability. My ex-hub wasn't a kisser. He expressed his love in other ways. Small kisses were okay ~ but, no tongue. He didn't feel comfortable with it. My new bf loves kissing as much as I do, which is wonderful!

Finding a person who enjoys what you enjoy is a real treat. I wouldn't worry about sexuality due to your avoidance of tongue kissing boys. If you don't feel comfortable with it, don't do it. Plain and simple...really!

Best wishes to you!
