it's his birthday very soon

I was wondering if anyone had any naughty ways of saying Happy birthday to him. Will post just a simple wish on his facebook wall but want to send him something a little naughtier privately.

Ideas so far:

Shame i can't be with you to be your birthday present, I think i'd quite like being tied up by you.

or i could just send him the song birthday sex (Will have a listen to recap as i haven't heard it in ages)

we had a falling out due to my mate a few weeks back but since then we've more than made up for it but I'm just wondering if anyone has any other ideas maybe something you've said or something someone's said to you? if you don't mind sharing of course.

Ok birthday ex is a guy singing to a girl but i can always just tell him to imagine it vice versa?

I saw some very cheeky/funny birthday cards on a well known high street competitor's website. If that could be your thing.

Ooh that'll be handy 😊will have a look now
