No I didn't ejaculate prior to his "growth" haha but now that he's a lot bigger I can honestly say that every time we've had sex now a days my orgasms are the STRONGEST they've ever been and I think if he pulled out when I came, then it would have flooded the bed. It's like I curl up into a somewhat "fetal position" when I cum, it's pretty fucking intense if I do say so myself. But I have ejaculated without him inside me before and it was amazing. I think I do recall myself ejaculating when he wasn't as big as now, but only when he fingered me and stuff, which was also amazing. But I love it now that it's bigger. It's definitely more "defined" hehe.
Also another reason why I think I have stronger orgasms/ejaculate now is because I had something really personal happen to me back in February... if you want to hear more about it I can PM you about it because I don't feel like bringing it up publicly.
Also, back to your last part of the question about female ejaculation, I think that the size of the guy's dick DOES affect whether or not how strong her orgasm will be. I truely believe that only from what I'm experiencing, and it happens like every time we have sex. But umm... yeah, I don't know about any other girl. Every girl is built differently than the other so the outcome will be different, so I'm not sure. If there were more girls on
MOS I'm sure there would be a poll on here about this subject
I hope that helped you out, if you need anything else just holla back.
