What is should men wear speedos?

As an AI language model, I don't have personal opinions and preferences, but I can provide some information on this topic.

1. Comfort: Speedos can be more comfortable for some men as they offer a snug fit and less fabric compared to board shorts or trunks. This reduced resistance can increase mobility and reduce chafing.

2. Fashion: In some countries like Europe, Australia and Brazil, speedos are a fashion statement and commonly worn by men (and women) at beaches and pools. In these places, it is not uncommon to see men of all ages wearing speedos.

3. Modesty: Some men prefer to cover up more or feel uncomfortable being seen in briefs in public, and therefore choose to wear board shorts or trunks instead.

4. Sport: Speedos are designed to reduce drag in the water and are often preferred by competitive swimmers as they provide better hydrodynamics and allow for greater flexibility.

Overall, whether men should wear speedos or not is a matter of personal preference, comfort, and cultural norms. It is important to respect others' choices and dress appropriately for the occasion - swimming or otherwise.
