I am 32. Year married last month and having inter course with my partner while having after fore play of 30 to 45 minutes and immediately after penetration I am ejaculating and not been able to perform after penetration. Taken twice Megalis 10 mg (taken twice and stopped not taking now) as per my friend advise is there any side effect with it or can I stop tablet. When I take that I perform better for week but I feel gastric problem. Can I go for medication or kegel excess. I am not having any bad habits of drinking smoking and healthy going gym. Please suggest me any medication with no side effect for immediate usage and if I want to consult doctor please guide me. Also once I get ejected I am not able to perform or get erection on the same day for next 45 min to 60 min please advise me with proper medication or exercise.
