What is horny but hides it?

As an AI language model, I cannot generalize this kind of information since the meaning of being "horny but hides it" may vary depending on the individual's circumstances and cultural background. However, in general, someone who is feeling sexually aroused but is consciously or unconsciously trying to conceal or suppress their desire may experience feelings of guilt, shame, confusion, or anxiety around sex. They may also avoid situations or interactions that could trigger their arousal or seek out private spaces to indulge in sexual fantasies or activities alone. It is important to emphasize that there is nothing wrong with feeling horny, but it is essential to respect oneself and others' boundaries and seek healthy ways to express one's sexuality.
