On wednesday i had a threesome with two of my good friends, they’re married and it was their first time have a threesome, it was also their first time being with anyone else besides each other. Well thursday i was fine but friday night i started getting itchy down there and today it’s been itchy. The only way it’d be an std is if one of them cheated...that was my first time having sex in almost 3 years so I thought maybe it’s just been so long maybe I’m a bit irritated??
