masturbation is not harmful and will not affect your ability to achieve or maintain an erection during sex. if you are having these issues associate with sexual activity -- your first sexual activity -- this could just be "stage fright" or performance anxiety. while there can be organic reason why a person could not achieve an erection the fact that you are not having a problem with masturbation proves that the blood supply to your penis is adequate the nerves are working and all systems are "go". if (and when) you find a caring partner try to relax and allow nature to take its course when it comes to sexual activity. if you are still having problems you may need to see a counselor to help you through this anxiety-provoking event. many fears run through a man's mind when first-having sex: will i be able to perform? will i please my partner? will something happen that will embarrass me? will i get an std? many things. let sex "happen". don't be anyone but yourself.
