well it may be the medicine but I talked to my doctor about it and he said the medicine - Xolair is not the cause.
Xolair is a new asthma shot I receive every 2 weeks in my arm muscle.

I am 22 and I have not been able to ejaculate while both sexual intercourse or masturbating. It is starting to worry me yet my doctor says it isn't the xolair shot... I am on no meds besides the xolair... the erection lasts only a hour but when I was 20 it would go down in 15 min when I did ejaculate....

can someone please give advice, should I worry... I do want to have children someday so from your opinion is this a cause for concern
