The thing is, they were making jokes about mastrobation towards each other as well, so it wasn't like they were singling me out. They obviously weren't trying to make me uncomfortable, because we had been joking about sexual stuff for the past 6 hours (it was over a discord call), so it wasn't like it was out of no where.
It's two boys, and one of the running jokes in our group is for one of them to make a joke that the other one is into me, which I honestly think is funny, and doesn't make me uncomfortable. I've known them for a while. I hate that it feels so much different for me to say anything about it than when they both joke about it themselves. Idk. We were all high on sleep deprivation too, which probably had a part in it. Idk what I'll do if the topic comes up again. Thanks for all the advice though!
