Flattered, or creeped out?

So, I'm 100% straight, but I have a few friends that are bi. All of them are married, but they all randomly make comments about wanting me to mess around with them. One of them mentioned me sleeping with her husband so she could watch? One of them doesn't even want her husband to know. Most of the time though they want it to be me and them, and let their husbands watch. I wouldn't do it, 1 because I'm not really into chicks, and 2 because I have a boyfriend and he's not cool with it since I wouldn't let him participate lol.
I'm just not sure if I should feel flattered by it, or be creeped out that my friends are lookin at me that way?

If they were suggested to do something behind their husbands back I'd be really bothered by that honestly. The other? Not really. I mean, you can have guy friends who think you're really good looking and that's not creepy. Why would women friends be different?

I'd be chilly-wagged, to be honest. That's just...totally awkward, and so not in the range of comments that need to be made.

Creeped out big time...

I'm bi, I've never hit on my straight or even my bi friends, that's just something I don't understand  

I mean, it's flattering when a friend finds you attractive- but pretty creepy when they put the moves on you, especially since they're in relationships.

They've never actually like, TRIED anything with me. I'm not sure if that's what you all thought I meant lol. One of them asked me if I would participate with her and her husband, or just her husband and let her watch. Another I met through SO, they all kinda messed around (him and his flings, her and her husband) at times when they were drinking. I'm the only one they haven't. She knows I'm not into it so she doesn't push the issue, but she made it known that if I was willing, she would, and told me once she had a dream about me and her with nobody else involved. I'm just not used to stuff like that.

My guy friends never hit on me or talk about sleeping with me BTW lol
