I have always enjoyed getting laid on my birthday.
But -- I also enjoy giving on someone else's birthday. When I was in college I had a number of close male friends - not really boyfriends but guys I fooled around with. I formed the "Blowjob on your Birthday Club" and have enrolled some of my best male friends. As far as I know, they all like their birthday presents. I hope to keep this club going for many many years. Tow of my charter member guys have gotten married - and both of their wives have let this tradition of giving continue - one of them has watched he hubby receive his gift. She suggested that I also "invert" the club for my birthday -- all the guys in the club who can come to my birthday get to "do" me, or get another bj. I'm thinking of proposing this for my next birthday.
I love birthdays.
