Once a week, most weeks, I will usually receive one from the wife. Very rarely will she initiate it twice in a week as we have intercourse more. For me, I have no problem with this frequency because any more would seem selfish and as great as a job she does, I prefer regular sex with her even more. When she does give a BJ, it is almost always to completion and we rarely do it as foreplay as once she puts me in her mouth and continues for more than a few minutes, I find it very difficult not to pop.
