So a year ago I was dating a very pretty but also experienced and kind of toxic girl. Basically she told me that I’m the worst kisser she’s ever experienced which didn’t surprise me since I used to be a typical high school virgin- overweight, ugly and short(I’ve had a good glowup I’m lean tall and better looking now)

but it’s been a huge insecurity ever since and I’ve never dated and rarely kissed anyone ever since that. Whenever I’m out drinking I always end up rejecting girls who try to kiss me because I don’t wanna disappoint them and embarrass my self (i used to be extremely insecure more than I am now if you can’t tell)

It’s not like I can ask someone to practice with me lol so can anyone help me out with some advice to be a better kisser?
