I think its one thing if she wants to like have a threesome with another guy, I mean thats actually a pretty big fantasy of mine.. but if she JUST wants to watch then idk that is a little weird..
Ok here's the thing my gf want to see me get fucked by another guy....I don't mind anAl with her an a dildo but I don't think I would be able to let another guy do that....would it mAke me gay to just do it for her
If you don't want to do it, just tell her. There are probably some things she's not willing to do in the bedroom & if she starts an argument just compare it to that. (I don't know your gf, so you'll have to figure out what those things are yourself.)
Would it make you gay? Would you suddenly no longer be physically attracted to girls? As long as you're attracted to girls you're not gay (& since you have a girlfriend I assume you are). I don't know if you're attracted to guys, but if so, you're bisexual.
