Two in a row is not the norm, but it's not unusual either, especially among younger men. If "in a row" you mean you can have another one in 20 minutes (especially if it's been a few days without sex), then it's easy for me, and I'm in my early 50's. Also,
orgasm and
ejaculation can be separate -- with the right stimulation and timing, I can manage to have just an ejacultation without an orgasm, and then an orgasm with little ejaculation, and those are exciting and different experiences of their own. But it feels more explosive and satisfying to just let go completely and have both things happen at the same time, combined with the driving reflex to thrust which provides more stimulation, until one reaches a state of dreamy exhaustion.<P>I think it is more common for women to have multiple orgasms than men.<P>On the average, single guys don't get laid as often as married people with good relationships. The simple reason is that it's hard to line up a new partner every single night, week after week, month after month. It's hard to beat the convenience of having somebody right there with you all the time, and you already know you're safe from STD's, etc.<P>Casual is often a disappointment, and leaves people feeling empty. But with the right attitude, context, and situation, it can also be very exciting (and that applies to both men and women). People who want to preach certain morals don't want you to know that, of course.
