doesn't seem to subside

Its kind of crazy how this fantasy of seeing her with a bbc doesn't subside. If anything it continues to get stronger. We haven't spoken about it for probably a couple months now and I was hoping it would die off a little bit but it just isn't. Any other wannabes experience this?
The urge can subside, but it never goes away and when it comes back it can be very strong. Hubby and I have not for many years now. I know he controls his urges, but at the same time when they hit, boy do they hit and he has hard time with them. Good luck, but based on experience on this side it is easier for girl to let it go then a guy at least in our instance.
