Maye he just has an overly active sex drive. It's not a bad thing. Now doing it all day long is a bit extreme so I suggest getting him out more so that his hands are occupied and that will build up more sexual tension so when you do get him alone, his hands will be on you. Masturbating together is another good idea. Maybe he does it a lot because he knows it turns you on and that's what he's trying to do. I'm sure his intention isn't to annoy you, but if he doesn't know that it annoys you, then he'll continue to do it and you'll continue to be annoyed. Because it's such a sensitive subject and you don't want to hurt his feelings or ego, try telling him with your actions first. Try putting his hands elsewhere and maybe he'll get the clue. If that doesn't work then ask him why he feels the need to do that so much. I hope my advice is helpful to you. On the bright side, he could be doing much worse so I don't think you have anything to worry about and that this can be easily resolved.
It feels good. Comfort zone to him. No matter if he is with you are not he is still gonna find pleasure touching his winky. He knows his body better. Then again if he isn't doing anything else throughout the day then he just being darn lazy. Be offended that he doesn't do anything else not because he is doing that. Tell him you need to do something like wash the car or do the dishes.
Its a comfort zone for them. Its always warm down there and , well, it's HIS. However, you may want to bring to his attention that he should also be considerate and wash his hands often, for sanitary purposes.
Be direct with him but not judgmental.
Ask him if he would think you weird if you did the same thing all day long.
He's not necessarily masturbating. A lot of guys do this, and in my case it happens rather often. It's not sexual at all, and it can be for several reasons. For one, sometimes it just itches really bad and I have to scratch it. It may be in an uncomfortable position. It may simply be that my hand was sitting idle and made its way into my pants for something to do. My girlfriend comments on this occasionally, but she thinks its funny because she does the same time sometimes with her boobs. For the most part though doing it doesn't even feel good. It doesn't feel BAD, but its just like rubbing your arm or so. Also, if my hand is cold I'll do it sometimes, because its warmer down there.
Next time he does that, go kneel at his lap and ask if you could help him out. That should give him an orgasm right there and then. ;) or if he does it then start doing it too in front of him.
