I'm no expert,and I only got it to happen a couple of times with the same woman,but it's unbelievable.At least for me,anyway.I think it's a result of a g-spot orgasm.Maybe it coincided with clitoral,she said it was like that,so that's all I really know.But,it was really evident by the way Her whole vagina seemed to pulse.Her legs went wild,and it got pretty rough,but I was well anchored and hung on.There's no way I could swallow all that came out of Her.It was like nothing that I had ever felt before from a woman.Taste was kind of like what Women describe with a guy.Kind of bitter,but the feeling in my head was like "who cares"..Seemed like it lasted a while,but I'm sure it was only a few seconds.As for volume.The bed sheets were soaked.My mouth and throat were full.My beard was even drenched..
I can't really tell others what to do,but for us,it was a result of a totally romantic night.Flowers,dinner,and a movie with Her kids with us.We necked for about an hour,after the kiddies went to bed,and then we went to bed,and I went for it.All I'm saying here,is that it takes a lot longer for women from my experience,but I have to say,it's REALLY worth it..No hurrying at all,and let Her guide all the way.Trick for the guy,is to hang on,after you find the g-spot and know that pleasing Her is foremost..Both times we managed to get Her that hot,we played for a good 2 hours,so I don't know if other women get there faster.
Don't know if that helps,but it's sure nice to remember,lol..
