Gecko "Puberty"?

My little male's been acting strange lately, not eating, always wanting to get out and be handled, roaming about his cage all night.

Tonight was cage cleaning night, so I took him out and noticed his nares were kinda red (it's been dry in my room), and then I noticed his pores were alot bigger than there were before and they're were little "strings" of white stuff hanging from them. There also seems to be a small vertical fold a cm or so above his pores that I've never noticed before. Maybe if he lets me I'll take a pic and post it later.

Also, he ate for me for the first time in 4 days yesterday and his poop was kinda wierd looking today, it was a lot lighter than usual and looked like a dolop of stuff rather than the usual turd shape, anyone notice this after their gecko goes on a feeding strike?
