Friends or more?

I have a friend that also would like to have sex...why would that be a problem? He is 8 year older than me and he refuses to tell me basic things about his life...he also refuses to have sex with me unless I give him a blowjob, which I would not like to do ...how do I get him to open up after 2months of us talking? How do I get him to stop asking for blowjobs when we hang out?
