I am 25 years old married male, during sex with partner my penis get ejaculated in 1 or 1.5 minutes after penetration. And after ejaculation I would not be able to continue sex due to loss of erected penis. I have to wait for some time (approx. Half hour) to get erected penis again and to continue sex. Earlier 4 years before my penis used to remain erect even after ejaculation and I was able to continue sex which is not possible now. Also now, in a day my penis erected and ejaculated only for 3-4 times continuously then after it would regain its original normal size and not be able to erect again. Earlier before marriage I had a habit of masturbation 2-3 times in a week. I want to enjoy long time hard sex with my partner. Request to guide me what to do to increase time of ejaculation and to enjoy continue sex even after ejaculation for a long time?
