Yes, women can be sexually frustarted by inability to get laid, too.

I hate it when guys get all "it's so easy for a woman to get laid, you just have to ask and any guy will immediately comply!"

But they conveninently leave out the part where guys are physically stronger and sex can be painful, and if you just invite some random guy over for sex how can you be sure he will be a good trustworthy guy who will treat you nicely? What if it starts hurting and you ask him to stop, and he refuses? What if you just want X and Y, but he decides that he also wants Z and forces it on you? What if you want to use a condom, but he refuses to wear it and decides that since you want to get laid that must mean that you want to get laid under any and all circumstances and forces himself on you? What if he takes naked pictures of you while you are sleeping and shows them off to his bros or even uploads them on the internet (yes, this happens)?

Even no-strings-attached casual sex requires a great deal of trust, it's not as simple as noticing a hot guy and asking him to fuck you.

And that's not even getting into the whole "men who sleep around are studs, women who sleep around are sluts" clusterfuck.
