Male Ball python cloaca opening?

[JodanOrNoDan]

I recently got a female ball python and now sometimes when i handle my male, his vent will be opened a little. Is this bad or could it just be a sign he wants to mate? They are housed right next to each other aswell.

You are going to need to get a picture of this. The only times I have had a snake open its vent when being handled was when they were getting ready to shoot something unpleasant out.
