Hi sir, I m doing well Thanks for choosing health care magic, I can certainly understand your concern towards your sexual problem , it is glad that you have a good sex life . I can suggest you to check your erection during sleep by NPT test ie nocturnal penile tumescence, which can rule out any problem with your erection If it s normal, I can suggest you some measures like avoiding alcohol and smoking if any, and you can start taking sildenafil , which helps in erection by stimulating nitric oxide ie NO production. Please mention your age and weight, and try to maintain adequate weight, to improve your sexual performance, and get back to me with the above details. Hope this information helps you...Please post further questions Thank you
