Shouldn't wet heat help PE better than dry heat

It’s been my experience that wet heat penetrates into the muscles better when I have a backache. Perhaps I’m comparing this wrongly to PE since we aren’t just dealing with deep muscles; but shouldn’t the idea still apply? The tunica is tough so wouldn’t a good wet heat soaking stand a better chance of getting it to give way? I’ve always warmed up with wet heat.

I always warm up with wet heat. and i’ve gained so it cant be bad
