I am admittedly concerned about my reaction. I am not, by nature, a jealous or angry person. I suspect I'll love it but if there is a negative reaction it will probably be a dull, deep pain. Hopefully I can abort the action at that time, but if not, oh well. I asked for it, right?
It might be easier for me to stomach if it's a 100% swap and I'm also enjoying the guy's woman at the same time. Again, sounds weird, but oddly enough it makes sense to me.
