Problems in school

Does anyone else have problems concentrating in school when they are crushing on boys? Ever since I started questioning my sexuality all I want is to be with a boy to try it out. Now i'm crushing on a lot of boys at my school, and i keep having dreams about them as well. Im too afraid to hit on them because there is a moderate level of homophobia at my school and pretty much everyone is straight, or if they were gay they wouldnt dare come out. Ive tried many different dating apps and have had no luck. I have a few lesbian friends who are scouting for me. I cant fucking sit still. Its not that im horny... well i am... but i just need validation over everything. I cant stay in the moment, im constantly worrying and craving a boyfriend to take into the bathroom stalls. LOL, alright what do i do? Thanks.
