bedroom requests. If it's something you are reluctant to post here, you probably shouldn't put it in an email

Many ladies don't like sex acts being mentioned in an email, for obvious reasons.

After the lady screens you and confirms the date then you make your appearance request to her either by e-mail or phone.  

Bedroom requests (assuming you mean certain acts, positions, etc.) should be made after you are in the room alone, put the envelope in a conspicuous place, and begun to get to know each other.  Remember, you shouldn't discuss certain things.

I have had some requests that might be considered inappropriate for a pre-meeting e-mail, but needed to be considered before the actual meeting.

In those cases I went through her screening first, then followed up with an e-mail letting her know that I had some special requests that required a certain amount of candor before the meeting and requested her permission to be somewhat candid.

Each time without exception her response was on the order of "sure, what's on your mind".

The catch is that you MUST be screened to her satisfaction before any specifics are mentioned, you need to ask her before you mention any specifics if she is comfortable with such a conversation, and you must at all times remain as vague and general as possible while still getting the point across.

Oh, and you need to be ready for the possibility that any mention at all may scare her off...
