I went to an Ann Summers party and I can honestly say it was one of the worst experiences of my life.
To set the scene - there were about 10 of us, I knew the host and vaguely new 3 others, 2 mums from school and one playgroup assistant.
The Ann Summers rep (who happened to be 6 months pregnant and drinking and chain smoking) started the evening on a lovely note; she gave us all stickers with our name for the evening and we had to address each other by this name. Mine was the tasteful, 'Bucket Fanny Annie'.
Then we had to split into groups and make a 'sexy' outfit for one of us using bin liners. The winning team were given a packet of drinking straws that looked liked penises. (Kill me now)
Then we had the great hilarity of a game. We had to pair up (I got the 20 stone playgroup worker) and simulate sexual positions with each other whilst trying to burst a balloon between us. There were several rounds 
This was followed by an interminable session of passing around vibrators, dildos, 'knicker critters', fluffy handcuffs and all manner of crap sex toys, with of course, the requisite shrieking from the guests. Let's try them on our noses! And then piss ourselves laughing. Not.
Of course we had the opportunity to try on some of the clothes. Lovely, not at all cheap looking
stuff like a cheeky little air stewardess or naughty nurse.
Much of the evening I have, thankfully, managed to erase from my memory. But I do think back on it as one of the naffest, tawdry evenings I have ever spent. Suffice to say, I couldn't find anything to buy.
