Am I Being Selfish?

My roommate accuses me of being selfish for these reasons:
1) He wants me to leave my skis and boots in my dorm over spring break so his friend, who doesn't have his own shit, but has the same size foot as me, can use it.  I am bringing my ski stuff home because I tore my ACL and can't ski anymore.  I am bringing my shit home now so I don't have to in May.
2) He always wants to use my GoPro.  I let him use it once.  He takes it a second time without even asking me.  I let him use it a third time.  Everytime, he complains about it because he doesn't know how to use it. 
3) We got a shitload of snow today.  His gloves are wet from snowboarding today.  He want to use a pair of mine.  I give him an old pair of leather ones, but no, he insists that my newer, not worn ones are going to work better and takes them.  The old pair are perfectly fine. 
4) He uses my printer all the time.  He uses almost all my ink, almost all my paper.  Do I complain? No.

I never complain when he uses my stuff.  I never ask to use any of his stuff, which is his argument why he is not selfish and I am.  His argument is that he lets me watch his tv.  I mean really?  When I tell him that I don't want his friend using my skis and ski boots, he tells me I am being selfish. 

So NS, am I not the most selfish person in the world?
