Hi, I'm 28 years old and my boyfriend of six months wants me to actively participate in a three some with a large man who is a wrestler. I am a 5'4" petite, 112 pounds, my boyfriend is 6'0" and 195 pounds, while the third party man is 6'7" and 340 pounds. I am afraid the third man will really be too big? He also really wants me to go down on him (the wrestler)! My boyfriend then is particularly interested in doing a double penetration. What should I do?
