Anal sex - two questions
I've been reading a book by a so-called expert on sex who
claims that during anal sex one should never a) cum inside
the rectum of your partner's rectum and b) never use vaseline
as a lubricant - only water-based lubricants. We're not
worrying about oils breaking down condoms - the claim is
that vaseline is not easliy absorbed and will upset the
delicate chemical balance.
I find both of these claims a bit farfetched, but perhaps
I haven't enough experience. Anyone have any evidence
for these problems?
