Hey Adam!
Erectile dysfunction can develop due to a variety of causes. Psychological stress, performance anxiety, depression, neurogenic disorders peyronie's disease, body image issues, medications, alcohol, smoking, drugs/medications, hormonal imbalance, radiation therapy, kidney failure, metabolic disorders, multiple sclerosis, hypertension, diabetes, prostatitis, urethritis etc. just to name a few. Anxiety and stress play an important role in the development of erectile dysfunction; and is the most common possible cause. At a primary level, I would suggest being a bit relaxed and working on the psychological factors with your partner. It might also be beneficial to get rid of factors like smoking/ alcohol/ drugs, if involved. In case this doesn’t work, I would suggest seeing your primary care physician for an evaluation of the above mentioned causes and appropriate specific treatment.
The normal semen could vary between while to yellowish between individuals along with the ejaculation time, while the semen volume man vary between 1.5 ml to 6.5 ml and variations between these are considered normal and should not be anything to worry about.
Hope this helps.
Take care!
