I think this is the place to ask it, (hope it is)

Any ways I'm a teenager and I've been masturbating, I've masturbated and ejaculated and now there are semen stains on my wall and probably my sheets.

I'm not worried about my sheets they'll get washed, but is there anything I can do to wash away the semen stains on my wall to the naked eye and black light? Or should I just paint the wall a new color so the semen gets painted over?

Id prefer a soulution which would let me just scrub the stains away but I've tried soap, antiseptic, and some other stuff and its not coming off.

Can anyone give me some other possible options?
