I get this too - always in doggy style - to the point I've felt myself go bright red during bookings. The only time I've ever had someone comment about it was younger clients, my attitude is most men 40+ have seen and heard a lot sexually that doesn't really shock them anymore and unless they seek to objectify you, they know sex isn't quite how it is in movies. Socks always take forever to come off, you get cramp, vaginas make odd noises from time to time...
