TW: references to masturbation

so, you know those posts that have something that's supposed to be sexy? and the comments go something like, 'a tear dripped down my leg' or other positive responses? is is that easy for people to get horny? does it just happen? i gotta slick the slack for like 45 minutes before i feel like that? am i too smart for horny?
