You don’t have to have sex. Ever. If you’re not interested, if you’re not into the concept, if the thought of it makes you ill, even if you just plain don’t want to, whatever the reason is, you don’t have to have sex. No matter what your friends say or what the TV says or what “society” says, you do not have to have sex if you do not want to have sex. You don’t even have to justify why not. If you don’t want to have sex, you don’t have to get anyone else’s approval. No means no, and if anyone else has a problem with that, that’s their problem to deal with.
