I dont see anything wrong with what he has to say, guys should be able to maintain an errection and cum on cue, but the way I see it there dosen't appear to be a lack of guys that can do that at the moment.
I dissagree with him and his comments about the volume of cumloads ,personally I like to see girls taking massive facials, I dont care if the girl likes it or not, maybe thats a generational thing.
