So my wife and i are going on a couples trip soon and last night she brought up that the other wife has mentioned that they are in an open relationship. We have never had a conversation about sex with another couple before but last night my wife started indicating she would be interested. I am also extremely attracted to the other couple and would love to fuck them\watch them fuck each other and my wife. I am thinking about flirting with them and seeing where it goes. The problem is i am way out of my league. My wife is no lie a solid 9/10 and literally everyone is attracted to her. I really lucked out when i was younger. The other couple are also both a decade younger and easily 8/10 or more and I’m a middle aged, hairy, very obese white guy with 3.5 inches of dick. So while i would seriously love to explore this addition to our relationship, and would love to enjoy the experiences i am fantasizing about, i will probably be too embarrassed to go through with it. I have never been confident about my body and have honestly missed out on chances for sex with many other people just because i am scared of disappointing someone. Btw i am quite skilled in pleasing my wife without my dick but I’m not sure that would translate to other people. So should i ease my anxiety and plan to avoid any possible embarrassment, or should i jump in the deep end and go for it? How do i get over my lack of confidence?
