Baby Monkey, I believe you are asking whether or not she will end the party upon your climax. You should be sure to inquire about that during negotiations and discuss which activities you would like to do afterwords. During negotiations, take your time, articulate your desires clearly, and do not hesitate to get clarification if there is even the slightest detail you are unsure about. You will have the most enjoyable experience that way.
Again, I would like to reiterate my view that you should not fear how quickly you cum or if you do at all. I have a friend who came after about 5 seconds of intercourse and another friend who occasionally has trouble reaching orgasm with his girlfriend. We cannot always have complete control over how our bodies react. Everyone is different and goes through different phases. There are many things great about sex and being with a woman aside from intercourse that I believe you will enjoy.
