Threesomes with SO ....

Ashley • Ashley eggers

Okay IMA get to the point my bf of 4 years been asking me to have a threesome with him, but I don't think i would be able to be or act the same after if we have one. I have been thinking about it but I don't know where I would start what I should say or do. Would it change our relationship ? I'm so confuse of what I should do ...I don't like the thoughts that once we have a threesome with another female they would start talking to each other behind my back or even worse.... Have anyone had a threesome with their long term bf or husband and/or have any advice for me I would appreciate any intake or advice

Thanks
