1. How many times do you think you've had it?
Several hundred's of times.
2. What age did you lose your virginity, providing you have lost it?
18
3. Have you done the dirty deed with guys and girls?
At the same time? Or, multiple guys and girls? (haha)
I have only had one sexual partner, so I would have to say no to either.
What do you think of people who have sex often, with many different people?
I am judgmental toward them. Though, there is some reason to be critical of the behavior, I am not completely justified in my judgement, this might likely be an arbitrary social and moral indoctrination from family and society. However, there could be some valid drawbacks to frequent sex with multiple partners in that there are STD's or unintended pregnancy, which can occur even with the presence of protection (especially the STD transmission), as well as intimacy issues if they choose to go monogamous. The second of these drawbacks is questionable though given that some societies do not value monogamy, and therefore, whether it is good or bad largely depends on how it affects the societal structure. Proponents of safe sex and sexual freedom (non-monogamy), will advocate that it's unnatural to be monogamous and that it has a physiological responses such as stress relief.
As I see it, in the US, having sex often with many partners, deconstructs socialization of sexual behavior and reprograms a person to do that which is natural and instinctual. Humans are not completely monogamous creatures by nature. The question is whether this deconstruction of socialization can negatively affect society and whether socialization of monogamous sex actual benefits society. Would monogamy exist in a world in which there was no indoctrination or the deconstruction of monogamy became rampant? Does the incremental acceptance of sexual liberty from monogamy have a negative effect on society?
I am not conclusive on the issue, but for my own sake, putting aside the societal moral complications, I would say that the shame to do that which I have been programmed not to do, has more negative implications on me as an individual, than the sensation of complete sexual freedom.
