Clumpy Semen, Soft Erection.

Hello friends..

I been reading for quite sometime here and am really nervous tbh.

Its only that after about an year of uncertainty i have finally even tried properly to look for a cure now.

Pls hear me out.

I am 28 yrs male and healthwise gen fit . Take a good healthy diet and am active in life. I have not been doing gym for the past 4 yrs. blame lethargy for it.

No real ailment apart from Vitamin B deficiency which was diagnosed abt 2 yrs back, and thanks to doctor's confusion, i didnt took the supplementary dose once every month which i should have been taking till now.

Symptoms i am facing:-

1) Clumpy Semen. (Maybe because of less of that clear liquid which accompanies semen. forgot the name)

2) Soft Erections, almost impossible while standing up. 

Apart from these two, i think my testes have become a bit more sensitive.  And my stamina is less which maybe due to vitamin B deficiency.

I do get morning wood which gen stays for few seconds but not for duration as they used to. They been less frequent as well.

My T level is within healthy limit.

No major injury in recent past.

For the past one yr or so, i have been in denial that anything is wrong with me regarding the sexual organ, but it really is high time that i discard that inhibition now. Still am very scared and embarrassed to visit a doctor.

a) Any help on what is the problem i am facing?

2) I should visit a Urologist, right ?

I hope somebody will dispel my fears. I am not sexually active as i am not married.
