When I was 27 or 28 I dated a 36 y/o for about 6 months. That was about 10 years ago. Seeing your post made me kinda curious to see what she's been up to so I checked out her FB profile and unfortunately have to say that she hasn't aged very well. And she was pretty freaking hot back in the day.
Anyway, just do what you want to do now and don't think twice about it. But remember that if you're not careful and don't take care of yourself with proper exercise, sound nutrition, and world class skin care products, the mid-30's through the mid 40's can potentially be a rough stretch of aging for the typical female. It's unfortunate but such is life. Remember, back in high school guys had to put with all the hot girls having alleged ?college? boyfriends and then while we were working entry level jobs in our early twenties, we had to compete with all the guys in their late 20?s and older who were more established professionally, better off financially, and wanted some fresh meat.
If you do decide to cut it off with this dude, the one thing I will definitely recommend is to end it with a bang. Literally. Go on a 5-7 day trip to a nice resort and just fuck your brains out for the entire time. Bring some toys, some hot lingerie, lots of lube, a couple tabs of Cialis and make it your goal to wear him out to the point where he will actually have no choice but to use the Cialis. I recommend
Villa 25 at Round Hill in Jamaica. The fact that Jamaica is such a shitty island and somewhere you would never want to go under most circumstances is actually a good thing in this case because you don?t want to be distracted from your fucking. On a better island like St. Barts, non-stop fucking might cause one to feel guilty about not taking advantage of all the other fun things to do. You won?t have that problem in Jamaica. :thumbsup
