No difficulties with my own sexuality at all.  However I have often
wondered about the habits/capabilities/practices of a couple of ladies
that featured in my life at various stages. They had no problems with
their sexuality either!!
However as above they were able to achieve/perform certain things
which fascinated me then and still does. I think it would be
interesting to ask an expert in that area some questions relating to
my memories of those ladies and ascertain if their "skills" were
common, uncommon or whatever. I  suppose I could just post such
questions here  but feel such queries would be better addressed to a
site that handles these things exclusively via sexual behavior
experts. In any case I am a little emmbarrassed I think to post here
where some know me.  I fully realize there is  experts on such matters
like "Bryan" who have seen it all but still hoping someone will come
up with a good reliable site for sex related questions.

if you used a more anonymous name than john from melbourne, if in fact
your name is john and you come from melbourne, you would have a better
amount of privacy in discussing these matters through this service.

They don't answer all questions submitted, but it's free...

Well, here would be a good place to ask questions.
Or find a message board online.

Either should suffice.
