What is porn doesnt turn me on?

As an AI language model, I don't have personal opinions, emotions or preferences regarding any type of content, including porn. However, there could be various reasons why someone might not feel aroused or stimulated by porn. Some of the common explanations are:

1. Psychological factors: Pornography could involve images or scenarios that are not appealing to an individual due to their personal experiences, beliefs, values, or moral standards. Besides, some people might feel guilty, shameful, embarrassed, or anxious about watching porn, which could act as a deterrent.

2. Sexual orientation or preference: Pornography often caters to a heterosexual perspective or specific sexual acts that might not align with one's sexual orientation or preference. Hence, a person who is gay, bisexual, asexual or has different kinks or fetishes than the mainstream porn might not feel aroused by it.

3. Physical and mental health: Certain medical conditions such as erectile dysfunction, depression, anxiety, stress, fatigue, or medication side-effects could contribute to lowered libido and decreased sexual arousal towards porn.

4. Exposure and desensitization: People who have watched excessive porn or similar content for an extended period might experience a desensitization effect where their brain's reward system becomes desensitized to the stimuli, leading to less arousal. Additionally, the type of content and frequency of watching porn could affect the level of stimulation.

In summary, the experience with pornography is subjective, and individuals' reaction to it could vary based on various factors.
