I can talk about it, if someone else brings it up in conversation (which rarely happens), but I have to force myself to swallow my discomfort first, and I’d never bring it up myself – why is that? The topics of conversation I’ll cover with my closest friends know no bounds – except this one. Is it just too personal? Because that’s how it feels. I managed to get one friend, who will discuss her bowel movements with me at the drop of a hat, to admit that she masturbates. But only when she’d drunk the best part of a bottle of wine.
