shy but with curiosity to try something exciting with a clean discreet couple that understand, appreciate and respect how big of a deal to step into this..

Discreet and Hygiene are both equally important.

You can't have fun while you're worried about other things.
perhaps just  just watching till we feel comfortable  nothing pushy, nothing forceful.
then maybe after we feel comfortable enough to do something... 
it has to be natural and spontaneous for both parties..
