Re: three man relationship
Never did attempt a three-way relationship. I think there are only a few that could do this.
Sex is sex & it used to be that people would never have sex with someone without being in love with that other person. But this being the 21st century, things have changed. I do not want to say people get sex & love confused but sooner or later the more sex you have with someone, the more love you will experience. And since you are in love with your partner & seeing him having sex with this third - it hurts you.
Do you have sex with the third guy? Have you told your partner how you feel? It seems that jealousy has reared its head. If you really trust your partner, be honest with him & tell him how you feel. Hopefully he will be caring enough to get rid of the third guy. And if not, ask yourself if you want to live that life. It seems you are not happy & you need to be happy.
