The glans being cold is subjective. Have you ever experienced it that cold without a PE device? If not, then the wrap sounds just a little too tight - or just that you’re not completely adjusted yet.
Then again, the tension might be a little too high - or just that you’re not completely adjusted yet.
Either way, try adjusting one thing at a time. Try loosening the wrap ever so slightly. If that doesn’t change anything, wrap it the way it was before and try lessening the tension slightly.
If either of those techniques doesn’t work, I’d suggest wrapping more frequently until this condition disappears. Also, no sleeping with it.
But all in all, it sounds like you’re getting the hang of it.
