[|Human|] I m 21 years old and my gf and I want to have sex more often but sometimes I can t stay hard in the middle of it even though it feels good. I have no idea why and I ve looked up things online about erectile dysfunction and sometimes it sounds like it applies to me and sometimes it doesn t. I want to know if it s just in my head or should I go to the doctor and get some pills or something? Like I m only 21 so do they even give 21 year olds Viagra or stuff like that?
[|AI|]  Degree understand your concerns went through your details. You are just 21, and you are able to get erection and penetration and hopefully full ejaculation when you have sex with your girlfriend. I think you are talking about occasional slackening of your hard penis when your penis is inside your girlfriends vagina. Such occasional slackening could be due to many reasons like stress. Therefore, I request you not to worry too much and read too much into this. I also suggest you not to prolong the sexual act too much. In that case also, penis slackens due to physical prolonged hardness stress. I don't see any reason for you start any medicines for sexual dysfunction. You may consult a psychologist for counseling if you desire so. If you still need my assistance in this regard, please use this link. http://goo.gl/aYW2pR.
