When I was in this age bracket, there was a huge emphasis on improving consent culture via graceful rejection, and it's gone by the wayside. Which sucks.
Twice in my youth (once in high school and once in college) I was in situations where I was asking someone out and I could tell they were calculating in their heads the risks of rejecting me, and both times I said, out loud, "you can say no, I wouldn't have asked if I wasn't prepared for either answer." And then they said no. This wasn't some spark of special wisdom I had - I knew to do it because feminist conversations among my age group brought it up regularly. This isn't happening nearly enough anymore.
More recently, I was really glad when we got to "rejection sensitive dysphoria" in my IOP program and it was one of those symptoms where the therapists really emphasized how it affects others. Because it does.
Being someone who cannot handle rejection makes you much more likely to violate boundaries, and yes, that includes sexual ones. Yes, you, reader who has never hurt a fly. If you don't want to stumble backwards into sexually assaulting someone, fix your RSD meltdowns. If you keep them up it's only a matter of time. Because if you're nice enough to interact with, but are known to have RSD meltdowns, guess what happens when your friends and acquaintances need to reject you?
