I need help. Has this happened to anyone else?

Ok so I’m Pansexual but I’ve only dated women until I was 18 when I met my boyfriend, and ever since I’ve done nothing but gain weight. It’s not birth control because I went off it for a couple years to see if it helped (nothing changed). I’ve gone to my GP about it. Not thyroid, Nothing. No charge in diet or exercise.

I’ve known several women who dated only women then got a boyfriend and boom they gained weight!

I’m not sure if there is a crazy hormonal reaction or if men are just so god damn annoying and stressful that we just blow up from stress.
