I just realised that "like it's your first time" has a positive connotation I guess, but like... motherfucker? Do most people have non-awful first-time experiences of sex? Between garbage sex ed and cisheteronormativity I just can't imagine. I doubt it was even momentous for most people tbh? Idk.
Picking up knowledge to use later is what I'd recommend
Reading some books on trans sex and such. FTW is a good start too.
It's far better when you know what your doing and get good with just touch and how to play with sensation.
Those are things you dont get taught. You can teach yourself tho.
