Do you think a writer must have had sex at least once in order to write about sex convincingly?
The context for this question is that someone recently messaged me asking for advice on writing sex scenes. I haven't had a chance to write back yet. Frankly, I don't know if I'm even qualified to give her any advice beyond some suggested links. At any rate, because of the person's age and certain things she said, I suspect she is a virgin. That got me thinking.
ETA: My question isn't about whether someone must have engaged in the specific sexual acts they're depicting, but rather have they actually been with a partner in some fashion, experienced an orgasm, and so on.
