There are a few things to consider when deciding what name to call your boyfriend. First, think about what he prefers to be called. Some guys prefer nicknames while others prefer their given name or a more formal version of their name. If you're not sure what he likes, ask him! Secondly, consider how serious your relationship is. If you're just starting out, it might be best to stick with simple terms of endearment like "babe" or "baby." As your relationship progresses, you can experiment with other names that are more personal or intimate. Lastly, don't forget to have fun with it! Calling your boyfriend by a silly nickname is a great way to show him how much you care about him.
