Thats the absolute worst
there were 2 guys in particular who were massive duds
One guy simply had low testosterone. Was decently hung but pointed straight down and couldnt even come close to getting it up. Afterward he said "i didnt think we would go that far so fast" So we invite you over to fuck my wife and you didnt think it would go that far?
2nd guy "forgot" to take a shower and smelled like he came straight from playing basketball outside in 90 degree heat.
To this day wife says "he would have gotten another inviite if he didnt stink....."
