So, i masturbate 1 - 2 times daily. Today after i masturbate, the sperm came out not as usual. The sperm is not too thick (Like water but a little thick), came out in a large amount, and gushing rapidly. The usual sperm is thick, came out in small amount, and dripping. This just happened 3 hours ago , and it's my first time getting that. Note that the sexual things i have done is masturbating, no sex or something.

Is there a chance i have a disease on my penis? 

Is it normal?

 

Thanks
