I am 32 years old married for more than 3 yrs. Before marriage I had masturbation habit and I do still when my wife goes to her hometown for months. Initial days of marriage I was able to have sex for 2 time a day but now I lost my desire for sex and I am also facing premature ejaculation. I am ejaculating within 30 secs or less. I have used stop and start technique but not enjoying the sex. I do not have any habit of smoking drinking etc. I also do not have any children. If I am having sex in other position like doggy style or other style I am getting overexcited and ejaculating within 30 secs or less. Please mention any particular medicine name which will help me in curing premature ejaculation and increase my sex desire.
