The best romantic birthday ideas for a man are the ones that show knowledge of what he likes. These can include taking him to an event he is excited about, cooking him something he loves, or simply spending the day together playing his favorite games and watching his favorite movies.
Another really fun and romantic idea is dressing up as his favorite female character from a movie, TV show or video game he enjoys. This can be an interlude to an exciting and romantic evening together and a birthday he never forgets.
A road trip is also a great idea. Look up places nearby that he mentioned he would like to visit, or some places that can be fun and spend the day driving, chatting, laughing and trying out new things. Visit the roadside shops to try out sunglasses, T-shirts and all other silly things tourists enjoy and do not forget to take pictures to remember the sweet moments.
A great birthday gift for a boyfriend is the one that makes him feel good. Writing 100 notes about lovable things about him is a romantic way to show affection and lift his spirits and confidence.
Some old-school fun can also be really romantic. Spend a day at the roller rink, paintball field, laser tag center or arcade to relive some fun memories and make new romantic ones.
