Red bumps and dark skin. Are recent?

Just today i noticed that the glans penis when i pull my skin to bottom i can very small reddish/whitish spot very small but numerous like not too many but yes around 20-30 spread uniformally over the whole head of penis (not the covering skin but the inside of skin i am uncircumcised) they dont itch, no pain or anything but they are even too swelled that they might burst but just like small bumps, And second thing like when my penis is erect i have foreskin, the uncovered area that remais of the glans is little darker in color then the rest of glans which is reddish whitish like normal i guess but due to those small bumps it kinda look a little more rddish, but there is no pain blood itch or anything, i just had sex twice which was way back in 2019 i dont even masturbate a lot,but i used to masturbate a lot 6-7 months back,the dark patch or its like tanned skin more instead of a patch, is present since i remember like at least 2 years but the bumps are recent
