Hopefully someone can help me with this but sometimes ive really enjoyed my time with someone i really wana tip but know they dont like any type of exchange of money during session is there an acceptable of doing this of should i just stick with leaving the money on the bed or bathroom and lettin them find it themselves?

I think if you add it at the end and say thank you so much I really enjoyed it here is a gift, that is acceptable. If you've already had the session there should be no worries about exchanging money. Or just add at the end in the bathroom and tell her to check it before leaving. Xoxox. Hope this helps.

It's really sweet of you to want to tip - but I get that you do not want to make it awkward. A simple kiss and voicing how great of time you had is simple enough + placing your additional gift down (without alluding to it) somewhere she can visibly see it should do.  

With many (including myself), tipping isn't expected -- it's more of a cherry on top -- but does leave a fond and lasting impression on the companion that you hope to see again!

Just slip it under the envelope when saying goodbye. Make no reference to it but your new friend will notice and thank you.
