I don't think you can call this a munch!...you may just have to reword it as you are giving preference to couples and single females......you better check out the terminology of what a munch is.
As Da69ve has just said this is not a munch, and cant be advertised on here as a munch. A munch is a social evening to allow members to talk and get to know each other, it is open to all regular members of the site (so no restrictions on males, couples or females). Link below will give you more details. http://www.swingingheaven.co.uk/terminology/munch.html
