i am 27 years old and i am getting married next year. but i am little bit worried about my sexual health as i have feeling that there something wrong with my pennies size and duration. whenever, i felt like having sex i was doing masterbition as i never had any physical contact with women yet so never experienced how it feel like. since i realised that not only my size and thickness of pennies is bothering me and also the duration. when do it fast it takes 30-40 seconds for erection and on slow it takes 60- 80 seconds.
