How would a male narcissist deal with sexual problems such as not being able to perform? Would this make them more abusive to others?

A male narcissist will often deal with sexual problems such as erectile dysfunction, premature ejaculation, and anorgasmia (inability to achieve orgasm), in a variety of ways. In some cases, they may deny the problem exists, blaming the partner for their own failures. They may project all other blame onto others rather than accept responsibility for themselves. Additionally, they might become critical or verbally abusive to seek control over the situation if it is not going according to plan.

In more extreme cases of narcissistic personality disorder, this lack of performance can lead to hypersexuality and engaging in risky behaviors such as infidelity or substance abuse while trying to “prove” their virility or worthiness as a man. Narcissists also have a tendency towards emotional manipulation - using guilt tactics and verbal abuse on their partners in attempts o divert attention away from themselves when unable to satisfy them sexually. This increased emotional tension only serves to add further strain onto the relationship

Therefore yes, sexual problems can make narcissistic people more abusive towards those around them due either directly reacting against these issues or by attempting indirect manipulations or outbursts designed o disguise their underlying sense of inadequacy/failure regarding sex/intimacy related matters within relationships..
