They don't like to be emotionally vulnerable
Erotophobia can affect someone's personality as well. It might make you more reclusive and introverted which will have an impact on your relationships in general.
If your partner has a hard time opening up to you and other people, it might be a sign. You can also tell if they don't have many friends or close relationships with other people in their life.
They avoid talking about sex
You can also tell by the way they take about sex. When you're with someone you love you naturally have a positive outlook when it comes to your sex but for someone with erotophobia, there will either be hesitance or total avoidance.
The thought of sex triggers anxiety and fear and that is why it feels better for them to avoid talking about it altogether.
They struggle with self-esteem
This problem affects different areas of your life including your perception of self-worth. It can cause you to dislike your body physically, which is another sign that indicates erotophobia.
Your partner might make negative comments about their body often and you will notice that they don't like to be seen naked.
You might have thought that it's just about self-esteem issues but when this sign is combined with others on this list, you might understand the root cause better.
