I am an older gentleman and I want to share my feelings regarding rimming or annilingus.
I only recently experienced it for the first time.  I had a masseuse finger my anus and massage
my prostate, which helped with the happy ending, but never had a tongue job.  I am a clean freak in most ways, so a tongue was not something I ever expected down there.  I have enjoyed a dozen or so Asian girls over the last six or seven months, and most of them are very adept at this technique.  I enjoy it so much, I browse reviews looking for those who offer it.  Some say they do, but don't, and that pisses me off.  I had one girl who actually got my rocks off as she buried her tongue in my butt.  I also now enjoy giving, as well as getting a good tongue job.  With both of showering our genital areas thoroughly, I never detect an odor.
I take Cialis (30mg) and if the escort is not friendly and good at how she performs, I may not get hard enough to really fuck.  However, I found that getting a good rimming and then giving a good tongue fucking to a cute little bung hole gets me hard and ready to fuck.  I have noticed that some guys refer to a "starfish".  I assume that is a nick name for a  girl's bung hole?  I wish that guys doing reviews would always mention, if not describe, any attempts or activities of this nature.  I can't have faith in the TER reviews that say Yes for the rimming question, since a few of these ladies declined to allow any such activity.    
   As you can see, I love it and am seeking girls who will return the favor and the pleasure.
