Is port forwarding safe for a minecraft server?

i want to know if port forwarding is safe to use just for minecraft, more specifically portforward.com
I am making a simple modded server just for me and my friends and would not be telling anybody else my computer s IP address, however I am not willing to have my computer wrecked just to play with my friends…
It would help if I felt secure in port forwarding, because I just won t do it if I don t feel secure.
also, will port forwarding effect any other devices being used on the specific router? Because it would be pretty embarrassing to have my mom knock on my door asking why her wifi is being weird.
