Only once, already as an adult.
A foid who was the ex-girlfriend of a bully-esque guy from a social group I used to hang out with started giving me IOIs through Facebook (this is not bragging mods, please read the whole story). We talked, I set a date with her and tried to kiss her, she turned her face.
Turns out she only did it to make him jealous, and made an intrigue between us. He came to me calling me a retard for even thinking she could be really into me and a false friend. I told him I never considered him a friend and didn't care what he thinks, I tried to kiss her, yeah, even though I was suspecting it was probably some shit like that.
He got visibly hurt from hearing that, lol. Also didn't have the courage to confront me physically. He retreated.
I avoided him after that and we never talked again.
