First tiimer here with a seemingly dumb question.  If I'm visiting a provider for incall service, is the expectation protection will be provided or am I expected to bring my own. I suppose it's best to be prepared, but I honestly have no clue what is considered common practice.

always,
be prepared for everything and expect nothing and
noone will disappoint you, including yourself.

expect her to provide also, but never go to a session without protection... 99.999999% of the providers will have condoms available, but there is the occasional "I ran out" "I forgot them" etc.....

Yes always BE PREPARED!

Just like going to a friends house and asking
"should I bring anything", never ask, always show up with a nice bottle of something

Good providers always insist on using their condoms.

It's just plain common sense.

Quote from Mr. Fisher:"Good providers always insist on using their condoms.It's just plain common sense"

I thought for sure you were going to put:
"It's just plain CONDOM sense"

LOL

Always bring your own just in case the lady is out.  As was also said, unless a morning wake-up date, bring along a nice bottle of wine to help set the mood.  Ask her first what her preference is (white, red, champagne, etc.).

That of course she would have them, but shit happens! I like my own particular brand, so I never leave home without them.
