Penis and semen question?

[Dimentio]

Okay i am SO embarrassed to post this! XD
But one does your penis shrink as you get older and two, What is semen meant to look like? Oh and one more thing i forgot, I cannot pull my foreskin back like i can till it is half way down the head, But after that, It just hurts and i cannot do it :/
As in about 3 years even though i just turned 17 i noticed my penis shrank like .5 of an inch o.O And normally when i am having alone time, Once i am done semen normally shoots out and it is kinda watery but with a whitish colour to it but with a clear outer layer, But recently when i did it again, It was all kinda thick and gloopy and slowly chugged out and had no clear layer and lumps, So since then i been scared to do it again haha, So yeah what type is normal?

not sure about the shining bit - maybe just how you measured??

anyways semen does change as puberty progresses .

this change is due to you producing sperm so it all ok and maybe you just need to get used to it and you will find you get some ejaculations which shoot and some which do not. or the mixture a shoot or 2 and then chugging out as you say

I once read that if you don't masturbate often your seamen can have lumps. Maybe that's why.

Semen comes out depending on what you eat believe it or not lol It also changes in 'taste'.
