That is a Interesting subject to talk about cause the numbers would be different, before we got married and after we did~ But for a total I could only guess and would know more about the numbers after being married.
Being a single guy I was always looking for a girl / woman that would let me cum in her mouth and if she swallowed it that would be perfect, but I had no luck till going to my buddy's BAR.
While sitting at the BAR talking with 2 regular guys there, we started on this same conversation about being able to cum in a girl / woman's mouth! To my surprise they both told me about a woman that came to the BAR every so often and if you got a chance to talk with her and Hit it off maybe you could get Lucky with her and she does both of those exciting deeds! They both said they had it done by her, but not at the same time and on a single basis.
So I asked my buddy the owner of the BAR to let me know when she was there and he did. It seemed like we hit it off and went for a late meal after the BAR closed, then we ended up at my place!
I can say those guys told me the truth, cause we ended up in my bed doing sex play.
While doing oral on my cock, she stopped long enough to tell me that I can cum in her mouth and she'll swallow it.
Then she went back down, but at the same time I told her YES I know! That's when she stopped to find out how I knew and I had plenty of explaining to do and that's another adventure! lol
But I started out knowing these 2 guys at the BAR that enjoyed my future wife First~ lol
