Dude, I came to the conclusion that sex is overrated 20 years ago.
The macho dumabass reply by a meathead would be "oh, you've never had good sex", but the thing is, I have. Its not that sex isn't a great thing, it's just that it's put on this pedastle as the end-all-be-all. The commercialization, the constant selling of sex (or more accurately, using sex to sell), the hype, the talk, the attention on it. Nothing can live up to that expectation/pressure. Nothing.
I tell ya this, if I'm compiling the greatest fun moments of my life, sexual encounters wouldn't make up the bulk of them. And every time I come out of a session with an SP, I always think "was that really worth XXXX dollars", and the answer is usually no. 1 hour with a fav SP = 200 say (plus or minus). For that, I can spring for about 4 trips to a Cactus Club with a good buddy or two having some food and some cold beers. And that will always be better "bang for the buck" (pardon the pun).
I still do see SPs of course, and I still try and nail my wife as often as I can get away with (sex is important to me, and she floats my boat big time), but perspective helps a lot.
