Dear kay_gii,

There are no visible signs on a man's penis or anywhere else on his body that appear after he has had sex for the first time. The only changes that may occur are changes in how people feel after they have sex for the first time — however they define it. People have many different emotions — happiness, confusion, fear, pride, excitement, disappointment, or a combination of these things.

Remember, when to start having sex is a personal choice. Only you can decide. We all have sexy feelings. But we don't always have sex when we have them. So always do what's best for you — do what will help you enjoy your life, and fulfill your plans for the future.

Hope this information helps!

Take care,
