Don't do it! Those things are for sexually repressed women who still think dildos are risque. They shriek at the sex toys for twenty minutes and then complain about their awful husbands, the colleague who used their mug at work and gave them a cold sore, and their slipped disc from 1992 that plays up when they drive. Trust me, there is NOTHING entertaining about ice cubes shaped like cocks.
Having said all that, well done for getting an invite. Might also be worth the horror if there are some women from Glasgow going. Best one-liners...I was at one where my friend's aunt from Springburn looked skeptically at the jar of stuff that you're meant to rub on your clit to make it tingle and said 'aye right, would it not be cheaper tae just use Vicks?'
