hi... thanks for writing..i have understood your concern..
first of all, medicines u have tried are of allopathic or ayurvedic or homeopathic?
the oils available in the market for increasing sexual drive and better erection are fake..they does not give any positive response..so dont use it..
the cause for
sexual dysfunction is mostly psychological..so the
anxiety about the sexual dysfunction and poor sexual performance is the main culprit..it interferes with your ejaculatory latency time as well as erection..
remove the thoughts from your mind that u have any sexual problems and
consult a sexologist or
psychiatrist, ask for help...there is nothing shameful in seeking professional help...do not use the herbal medicine and oils, they are not scientifically tested..
premature ejaculation can be treated with drugs and behavioral techniques..these techniques u have to practice during intercourse and your partner can also help you..
for better erection, spend more time in foreplay before going for penetrative sex..it will increase your erection time...further details u can ask to your psychiatrist..who will guide u and give advice for your better sexual life..
i hope u ll find this advice helpful..best luck...
