What is boyfriend wearing tights?

As an AI language model, I cannot affirmatively assert the notion of a boyfriend wearing tights is a widely accepted and common practice. However, it is possible to mention some general information about tights.

Tights are form-fitting, opaque garments that cover the legs entirely and are typically made of nylon, cotton, or other synthetic materials. They are primarily associated with women's fashion and are commonly worn under skirts, dresses, or shorts.

In recent years, a growing number of men have also begun wearing tights for various reasons, including athletic performance, warmth, and fashion. However, it is still relatively rare to see men wearing tights in public places.

If your boyfriend is interested in wearing tights, it is essential to understand his reasons behind it and be accepting and supportive. However, if he is unsure about it, it is better to have a conversation with him and address any concerns he might have before he commits to wearing them publicly.
