My wife and I have sex once a week on an average. We are in our forties, M-45, F-41. We typically start with mutual stimulation, some oral 69 to warm things up and then I continue with detailed foreplay and teasing while she lays back and enjoys. Her moans indicate that she likes it that way. Due to the detailed foreplay and her favourable responses, I typically become turned on and hard in 5-7 mins. The problem is: at this stage she sometimes wants to either suck or stroke my penis. While this can be bliss for both of us, I can't let her because when I am turned on, I am already at a breaking point and a tug or a suck on my penis will make me come. Due to this reason, our orgasms have always been serial and never simultaneous - I continue with cunnilingus and fingering till my wife cums. I follow by penetrating her and letting myself go overboard. Even if I penetrate her without waiting for her orgasm, I am not able to hold my hardness for long. 1. Are these similar to the symptoms of Premature Ejaculation? 2. Should I try start and stop to continue being hard yet not ejaculate? 3. When we had planned for children, we used to have more frequent sex and in those days I remember that I could hold on hardness for a longer time. Please advise what can I try to improve my situation. Any suggestion is welcome. Thanks in advance, smukherjee
