The lifestyle has improved our sex life, we both now do things we never thought of do before and we both get off on having a friend join us in bed, we go to hotels, campgrounds, parking lots, our house, his/her house and on a cruise ship.
It can make you feel like a lesser man but she doesn't necessarily think that way, and sex is to be enjoyed.
Our sex life only got better after bringing in other people.
Are you looking to get a wife pregnant or just having the fun trying?
We did this with another man and we all got off on it but there was no pregnancy, just fun for them and humiliation for me.
