Your not alone avg-dick.
My wife was always giving me blow jobs when we were dating and first married. After the baby was born NOTHING, almost 2 years now without a blow job. My wife loves me to do her orally and wants it all the time which I'm more then HAPPY to do. I just wish there was someway to get her back into the sucking action. I keep asking her to do it, but she just says not now, but soon. If you find an answer let me know.
