Friends with benefits (virgin)

So I’ve never had sex before (I’m 18). Never had a boyfriend or anything like that. However a couple of weeks ago my friend who’s a guy after a night out started messaging me and sent some dick pics. Later that week we were talking and he was like do u wanna do something. Neither of us want a relationship but we both wanna have sex. He’s a good friend of mine so I know he’s gonna be nice and not take the piss about it being my first time and all.

But does it make me slutty or a bad person to lose it to a fwb thing cause one of my close friends says it kinda does.
