Dear user, Thanks for writing to Healthcaremagic. I understand your concern about effects of masturbation on sex life after marriage. Masturbation for sexual pleasure and satisfaction is normal. It is not a disease. What penis does in vagina during sexual intercourse, same it does during masturbation in your folded palm. Sex with h partner does not cause any harm, so how masturbation can do? Reality is exactly opposite. For example, if one is well versed in English language, he can learn French quickly. Same is between masturbation and future sex life. Penis size has no effect on sexual satisfaction of the either partner. ‘’Bigger is better’’ is very rampant myth. Don t let myth ruin your sex life. Only lower vagina (outer one and half inch) lips and clitoris is sensitive, deeper part is largely insensitive. You remember that what important is strength and not the length! Entry and to and fro continuous movements are adequate. It is men s technique, not his penis size that characterizes the lover in him. Premature ejaculations can be overcome by techniques like.. 1. Stop-start technique of behavior therapy. 2. Female on top with active role and movements. 3. Double condom 4. Medicines like Fluoxetine 20 mg day or Paroxetine CR 25 mg per day. (To be taken under medical supervision only) 5. Kegel exercise also helps in some cases. You can learn the same from internet. (As if try to hold urine intermittently during voiding) 6. Penile squeeze technique applied at the point of ejaculatory inevitability. 7. Applying a local anesthetic ointment to glans penis prior to penetration. 9. You should do masturbation before sex (at least 2 hours before). It will make seminal vesicles somewhat empty. So, at the time of sex, semen will take more time to come out. If you have any query, feel free to ask again. Wish you good health.
