Iguanas are generally solitary animals and do not form strong bonds with humans the way some other pets do. However, there are a few signs that an iguana may be comfortable around you and may even consider you a source of security:

1. The iguana allows you to approach and handle it: If an iguana is comfortable around you, it may allow you to approach and handle it without displaying signs of fear or aggression.
2. The iguana becomes less active: Iguanas are generally more active when they are stressed or anxious. If an iguana becomes less active when you are around, it may be a sign that it is feeling relaxed and comfortable.
3. The iguana displays relaxed body language: Signs of relaxed body language in iguanas may include an relaxed tail, a relaxed jaw, and relaxed eyes. If an iguana is displaying these signs when you are around, it may be a sign that it is feeling comfortable and secure.

Keep in mind that iguanas are not as expressive as some other pets and may not show affection in the same way that other animals do. It is also important to remember that iguanas have their own personalities and may not behave in the same way as other iguanas.
