Sounds like someone is lookin for love....

Give him a week or two and then try him again.

Or, better yet, take him where the women snakes are and let him sew some wild oats.

He'll be back to normal in no time if you do, in a few weeks if you don't.

So long as he isn't losing a lot of weight, don't worry about him.

I am assuming he is an adult, not a baby.
