Only two: my boyfriend and a guy we had a threesome with. He's been with a ton of guys, though. On the one hand I'm envious of him because I was too shy to put myself out there before I met him and feel like I missed out on a lot, but on the other hand I'm glad I waited for him to be my first and that he's up for having threeways so I can still see what it's like with other guys.
