I am 17 years old and am in a very serious relationship with my girlfriend going on six months now. we have recently become sexually active but only succeeded so many times. I have been very stressed and worried because for the last four months my libido has been extremely low, I have had weak erections, trouble maintaing erections and am usually only aroused by physical stimulation this is in conjunction with my penis being tense on occasion when its fully soft and nowhere near an erection a dull ache and an impersisten pain that sometimes occurs at the ejaculation hole.The only problem is anxiety is definitely a factor to some degree because I have gotten a very hard erection while merely holding and kissing my girlfriend but this occurence is inconsistent. there has been days where it is the least bit hard you can imagine and will not go away,and mornings where I either have a weak or no erection at all. I have talked to doctors,psychiatrists been taken off medications attended therapy for the anxiety and still nothing.I even have lack of feeling considering every time I have sex with my girlfriend ALL 4 TIMES i barely feel it but Ill always come any input would be greatly appreciated thank you.
