Normal in Singapore society at large? Nope.
There's many that does this, but many more aint doing it. So its
not normal. ( interms of having sex with an external party with
your legal partner involving in it.) Though Anal is ohhkeh, if its
with ur legal partner married partner :D
Erm, maybe can do a test, tell ur in laws and parents or your
family members about this activity, if they are ohkeh with it
then...normal lorr....if there is any objections...i guess its
really not normal. "Ma/Pa, im making love with my hubby tonight to
get u a grandchild" vs " Ma/Pa im making love with my hubby and
another guy together tonight to get u a grandchild"
