Hi so im a 17 year old male ive had sex about 10 times so far so just last night me and my partner were having sex and we were unprotected and we had sex for about an hour straight i had to finish at least 12 times but every time i pulled out i just couldnt finish even right after she would go down on me and i just wouldnt be able to finish its almost like my dick was holding back more than my brain was telling me to finish and this caused frustration to me is there anything that could be wrong, she is tight so its not her fault im just confused at why i never came every time i would pull out while being on edge of point of no return. thank you for your time please someone help if you can. im not trying to go to a doctor yet in case this is something serious (the time we had sex before i finished but this time i didnt..)
