I might be worrying to much, but here goes: The other day I was fingering
myself in the bathroom. However, I remembered that I share the same bathroom
with several other men. I know for a fact that most of them masturbate in the
bathroom too. Is it a possibility that they may have left their semen in the
bathroom, for example on the edge of the sink, and that I touched that semen
and used the same hand to finger myself with? What are the chances of
getting pregnant this way? Thank you

Unless it's reasonably fresh and still moist, sperm will not be active and capable of causing a pregnancy.
I would hope these guys are cleaning up after themselves! If not, invest in some Clorox wipes ASAP!
