If I can't repeat with a girl - or envision the possibility of repeating - I won't take the plunge for the first visit. If I like a girl and enjoy the session, I want to repeat. Not being able to repeat is more frustrating for me. I will repeat 20 or 30 times with certain girls that I like.
That's why I never visit any girl who puts an ad on BP that says 'here for a short time only'.
The sexy ones are too addictive to only see once.
