If I am in a too-warm room then I find it impossible to keep erect.  I do much better in a cold room.

Yes it is, newbie1972,

Particularly if you have low blood circulation [as it seems you do.] Keep warm by exercising and yes, raising the temperature in the room.

Everyone's different in this case,

Hey newb72, I have the same problem when visiting a provider in a cold room.  Remember, you're coming in from the outdoors while she's been in that room for a while.   Try this:

Don't strip down immediately, give yourself some time to acclimate to the room.  During foreplay, tell the provider that you're cold & if it's ok to leave your shirt on for a bit.  It helps to talk to your provider--she wants you to be comfortable.  She'll usually bump up the heat and after about 10-15 minutes, you'll peel that shirt.  Hope that helps.

I tell you though, one of my best sessions EVER was in a cold room; the provider had just booked the room, it was the middle of winter, and we were both freezing.  We had never met before, but just to generate some body heat, we became intimate really fast (oh yeah!).  --z
