Tricky question for a couple of reasons:
I gig the occasional weekend, so when I do play out that adds three hours to that week, plus we usually practice a bit more in anticipation, so there might be a few more there. Some weekends I get to spend a lot of idle time noodling on my guitars, some weekends I never get a chance to pick one up.
And...I don't always play PRS (shhh!). I mess around on an Epi Casino I keep at the girlfriend's place, plus occasionally I want to play my Strat, or LP, or an acoustic (I don't have an Angelus...yet).
So in total probably a bit over 10 hrs a week total guitar touch time, averaged over a couple of months. But probably a bit less than 10 hrs per week of PRS-touch-time...
