I asked my gf to get tested for STIs

She's(22F) had quite a few hookups (including strangers) but I've (25M) just been with one person (me ex) before. I got myself tested recently(for a surgery) and came out negative.

I told her we'll take the test together for safety reasons and she's been upset since. She says if she tells this to her "progressive friends" they would ostracize me for being judgemental. I said I don't care.

She loves me more than I do, and she's one hundred percent loyal to me rn. But she's had her fun already and wants to settle but I don't think I'll ever be comfortable with people who've been okay with casual sex.

I'm confused but I feel for her as well.

Any suggestions? What am I doing wrong? 🥲
