Any advice for session?

Well I finally get a chance to sleep in because I'm done with classes so tonight I'll be having a session. I've started getting back into this so I'm not quite where I used to be. Things aren't as sensitive for me anymore so I'm struggling with that. I've been trying to not put too much expectation on my sessions and that has definitely helped

My main problem is one that I know a lot of people have. I get to the really good spot where I can feel everything rising and then it stops before crescendoing. Any advice on how to get past this?

Also I ran out out of ky water based lube so is lotion okay?

Thanks everyone
