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.
My first was definitely a positive experience. It was my high school (and later college) girlfriend. We'd been together for almost a year by the time we did it, had fooled around extensively in other ways (and so knew each other's bodies and likes pretty well). We talked openly about it before we did it, decided we both wanted to, and made sure to use a condom even though she was on birth control. It was sweet and fun and a great memory. I'm still friends with her, and she and her husband give my wife and me free weed that they grow in their back yard. All around very cool and wholesome.
