I think if a guy has had like 6 or so different sexual partners then that's close to ideal for let's say a 27 year old like me. That's not too many and it shows that a decent amount of women liked him enough to sleep with him.
As for the debate of being a virgin, is it a bad thing? If you are a 27 year old and a virgin, yes, it's a bad thing according to most of the women out there. Those MTV shows aren't that far off, much of society views sex as an accomplishment and "normal people do it."
In my position, I've only had sex once so I'm pretty close to a virgin and that's a bad thing according to the majority of women. Obviously there is a good thing, it means I'm clean, but the thing is they know you are weird immediately when they find out that you haven't had a "normal amount" of sexual partners.
Human nature doesn't like shy or weird. Why do you think so many people hate Tebow? Because he's super religious and unusual. There are only two reasons someone passes let's say 23 years old and is still a virgin: Either they are very religious or they never go out due to shyness issues. Both of those are bad in a lot peoples' minds.
It's a turn-off to an outgoing woman if a guy is shy in most cases. The low number of sexual partners makes things far worse because the woman views you as unpopular and thinks that women don't like you enough to have sex with you so there must be something wrong with you as a person or in the sack.
If you ask me, I think a guy is much better off having had sex with 40 different women than having had sex with 1 woman. I know that sounds messed up, but it's true. Women say they care about clean but what they really care about is social confidence and social status. Sex is a big part of social status.
It's not quite the same with men viewing women that way. I think the virgin thing, though, can definitely turn a man off once a woman gets to a certain age. The reason for that is men usually want to have sex eventually and they don't want to have to wait forever for it or have the possibility of not even getting it.
If a woman has had sex before though, even if it's with one guy only, then men won't care.
