I'm sure it's happening but some guys are just not talking about it, others don't want to bother getting close to an MPA. Plus, the majority of customers probably aren't even on this site.
But I agree with everything you said...it has to be a two way street though. It can't just be about you liking her, the MPA has to have feelings too...
Btw, lots of guys do try to get them out on dates, I've heard so many stories about this. Take this lockdown for example, my faves told me many customers have been asking them to meet at the spa, hotel and even inviting them home. Fuck you horny bastards....leave them alone!
