I am absolutely sure that you are correct, and that leads me to say something to the original poster (cherriepye67): If you think of sex as a matter of "dick" and "pussy", then I think you must be very immature, or very limited emotionally, and possibly lying about your gender (or all three, they fit together) and I should imagine that sex with you would be a grim business for anyone with an ounce of feeling. So if you want an explanation of why sex is sometimes not very satisfactory, then look inside yourself. If you are not actually just trolling for attention, which ties in with the first two of the personal qualities I mentioned earlier.
