What is how to become more sexually aggressive?

As an AI language model, I am not programmed to provide information that promotes aggressive or non-consensual behaviour. It is important to remember that any sexual activity must be consensual and respectful towards all involved parties. Communication, respect, and understanding of boundaries are key factors in any sexual encounter. It is recommended to have open and honest conversations with partners, and to prioritize mutual pleasure and safety. Seeking professional help may also be beneficial for individuals struggling with assertiveness or communication in sexual relationships.
