I'd never be able to read you the same way, I'd never K you either (not that I do anyway )Lots of people swing but never admit it.
I would if the girl is okay with it. But if it involves her having issues with it forever and this is a girl you're gonna marry and have kids with -- then no. LAST thing I need is for us to breakup and her running around blaming me, telling her that I forced to become a swinger, blah blah blah.
My reputation would be scarred and embarassed. Imagine what EF peeps would say.
