Hi doll! I personally prefer outcalls to incalls.... but as far as screening goes, get references. Get a description of him physically, get his phone number and email and do some research. Check his board presence on here... make sure his posts align with your ideals because you obviously wouldn't want to meet someone you wouldn't be compatible with. If everything looks good, then proceed with the outcall appointment. Hotels make me sketchier than homes, I don't like visiting them but will for regulars or out of towners.
Hope that helps, you can pm me if you have more questions.
