Is it normal to have a younger friend who likes getting blowjobs?

I have a younger friend who likes to come over and watch porn videos because his mother forbids him to watch them at his house. We've been friends for months when he asked me one day if he could watch a video at my house. I said no problem and he could watch his movies anytime. I didn't know at the time they were porn. So one evening he comes over and puts on a video. I liked them as well, always have. He started playing with himself in the beginning then he returned from the bathroom one time with an erect penis and basically put it in my face. I ended up obliging him. Is this normal behavior for a teenager to want blowjobs?
