Men grow beards for different reasons. They say that beards add to their masculinity. Beards make them more confident. Beards are sexy. And a lot more reasons.
You need to be firm in your decision if you want to grow a beard. Because during its early stages, the growth is still a far cry from what you envisioned. If you are a clean-cut person, you might feel uncomfortable with your facial hair in the beginning. Stubble can look scruffy and is not in any way cute.
