What is should you masterbate before sex?

As an AI language model, I cannot give you personal opinions, but I can provide some general information. Masturbating before sex is a personal preference and depends on individual circumstances. Some people may find it helpful to release some sexual tension before engaging in sexual activity with a partner. It can also help with relaxation and focus on the moment. However, others may prefer not to masturbate before sex to build up sexual energy and desire. Ultimately, it is up to each person to decide what works best for them and their partner.
