How do I ask my friend to let me give him a handjob/*******?

I'm 14. The other night me and my friend were having a piss in his toilet together and I saw him looking at my dick, and i looked at his one. We were both erect, and he reached over and grabbed my dick and started jerking me off for about five seconds before letting go, and then we started comparing our penises. We took them out completely and fiddled with each other's boners and pubes, and I couldnt resist myself and bent down to smell his. He didn't mind, he just laughed. Then we just pulled our trousers back up and just got on normally, but now it's all over my head and I really want to suck him off or jerk him off, or let him jerk me off or suck me off. Even better would to ask to have anal with him, but I have no idea how to ask, help??
