weird ick thing

for some reason everytime i become friends with a guy in particular, i get the worse ick feeling and i hate them so much, but after awhile it goes away and i have zero reason why. like it’s not that they’ll even like me sometimes, i just get annoyed and icked and it ONLY happens with men, it used to only happened when one would confess but now idk even if we’re just starting as friends i get so icked like??
help how does this stop like i don’t want to be mean or hate anyone for no reason (fyi i don’t really do anything besides ignoring them when the ick hits)
