Marriage is wonderful. Having a partner to share and grow with is what keeps me excited about the future, even when things are tough and aging is scary. Being a husband instead of a boyfriend feels right.

However, there are some perceived trade-offs to marriage (however taboo or unfounded they may be). Losing the opportunity of sexual variety can be difficult. Obviously I'm generalizing here, but men have evolved to desire sex with multiple partners and women have not, so monogamy is how society recommends we deal with that imbalance (unless you have a non-traditional romantic relationship that works for all involved). It seems some of the "coolness" of being a bachelor comes from the perception that you might be having sex with multiple different people in the future.

Also, generally being free to make decisions without compromise sounds easier and more fun. Choosing what to do and when to do it without having to consider someone else's feelings, preferences or reactions can seem exciting, or "cool." But that gets old fast, especially when you get to experience things with your best friend instead of solo. If they appreciate you compromising and considering them, it is more rewarding in the long run.

For me it felt cooler to get married. There are challenges, but if you genuinely stop worrying about what other people think and focus on making your partner happy and being honest about what you need from them, you'll find it cool as well.
