Sex Health

Okay, so I'm being very careful and sexually safe about this relationship that I am currently in. I've never had sex before, but things have gotten "heated" on multiple occasions between this guy and I. So, I know all about STDs and how they're contracted by the exchange of bodily fluids etc, but is there anything I should be worried about concerning things like fingering? I read that if they have an open wound on their hand you might contract something but... I'm a bit nervous (possibily a little paranoid) and this is all pretty new to me so...
