Hi I have a few little white bumps on my penis head, I have been told they are seamen glands? But more are coming up lately, what is the cause for them to increase? 
a bit clearer picture
I think you mean sebaceous (oil) glands. Yes, that’s what they are. No treatment needed and nothing to do with sea-faring men.
Adhari
Oh yes that is what I meant, is there any reason for them to multiply?
And are the bumps on my foreskin just I grown hairs?
Why now? These lumps and bumps tend to be more obvious during adolescence as they are affected by sex hormones (testosterone). If you are in your mid-teens to early 20s that would explain a lot.
Ingrowing hairs? The foreskin is actually a hairless structure! Are you referring to the small ‘bumps’ around the circumference of the glans in the last photo? These are coronal papillae and are quite normal.
Adhari
In the picture i can see keratin deposits and penile pappules. both of which are completely harmless. i have both of them in my penis. not to worry about that.
Thank you, is there a reason why it would multiply? Or it just happens?
Oh okay yeah I’m 23, I mean the little lumps on my shaft skin.
They are sebaceous glands (as above).
Oh thank you for clearing that up for me

I’m sorry to bother you. I do not know if I told you that they are caused by hair follicle.
Have a great day…Ken
I told you here just in case someone else wanted to know…
