All of us that have had sex or will have sex take this for granted but have we ever asked ourselves what is in a vagina that makes men ejaculate? Do all vaginas cause a man to ejaculate or maybe some do help a guy cum faster than others. My theory is the rugae or ridges inside the vagina but I am not a gynecologist but curious to know if I am on the right track.

My 'bro science' take is that I think it's just general friction of the glans head against anything it comes into contact with... mainly the vaginal opening, but the whole vaginal 'wall' and even the cervix, if you reach it, would be equally stimulating...
The ridges you speak of are likely a contributing factor.... I know they were in a the fleshlight models I've gotten to try over the years... Takes longer to clean those bastards than it does use them... lol.

It's all about friction, have you ever had a bj? The same question can be asked about being jerked off or having a bj. The male penis is extreamly sensitive with far more nerves ending then anywhere else. When my bf evacuates in me I can feel him tense up, hear him often giving off superlative's ;-) that tell me how sensitive it is at that moment. If it's real intense I normally don't grind or move until he's finish. Women also see that when we give a bj, or jerk a guy off. My first experience with my first bf. Making out on the couch. I was 15, him a year older. Sitting his lap many times noticing him hard, but one day he was on top and we started grinding. We both had on shorts, mine were mini. Both of us moving and kissing and he suddenly was like Ohhh! as his body jerked. Next thing I noticed was a wetness on my thigh. He was rather embarrassed but I said it was okay. I had heard from gfs that they had made a guy cum in his pants by grinding, even during dancing. Although he was embarrassed I felt quite proud of myself.... but to your point, it's all friction.

@mod. its not just the glans. the sensation of being balls deep in a girl is very stimulating.
but if the glans is massaged by the vagina opening (polishing the helmet) that is really nice.
but it isnt just the sensation on the penis. its being with a girl and playing with her body during sex. playing with her arse or tits. and/or deep kissing. or even watching ones cock sliding in and out (Girls like watching too!) and hearing her vocalisation and watching her face contort.
sorry if too gender specific. but you get the idea.
