My fiance has mentioned a few times now that he really wants to be in a M/M/F threeway. He tells me that he wants to see me getting pleasure from two men at once (he likes seeing my more naughty side). He's even said he would be okay with me picking any man I want, as long as I trust him. I'm not against the idea completely, but... I have such low confidence and self-esteem that I can't even imagine another person seeing me naked or even mostly naked. My fiance was my first everything (except kiss) and it took me years to let him see me even mostly unclothed. I can't imagine letting someone see me so exposed.
I know he wants it and it's a big fantasy for him, but I just can't. I've told him this before, and he seems to understand. He doesn't pressure me or anything, but I wish I could do it for him...
