We have been VERY successful in making friends via this site. We have met over 10 couples and singles (we have not played with them all, however, we have maintained a friendship with the majority). Not one person/couple has ever "not shown up" for a prearranged meeting with us.
We may just be lucky??? However, we think that experience and patience does contribute to our "good luck". We have found that chatting here and getting to know folk has definitely helped because it gave us the opportunity to convey that: meeting us in person is not a guarantee or promise of sex......this takes the pressure off everyone and things then can take a natural (sometimes VERY sensual and sexual) course.
PS: in the previous comments about " organizing a gang bang for the Mrs where none of the guys arrived" or/and in the case where "strangers" are invited to a pvt party. As sexy and exciting as these scenarios may initially appear/sound to the folk being invited, when it comes to the actual event ie when the reality hits home, a lot of people may be too nervous or afraid to actually follow through as they realize the pressure is on to perform.....
