I want to do something amazing for my boyfriend

me and my boyfriend have been together for 6 months. we have known eachother pretty much all our lives because we went to pre-school together but we have never been friends until his senior year / my junior year. we started talking when he would ditch one of his classes and would come sit with me and my friends durring my lunch hour. he kept coming to my lunch everyday to just sit next to me and about after a month he was caught lol but anyways he asked me to the homecoming dance with a build a bear he made for me and of course I said yes. the night before homcoming he asked me if I wanted to hang out with him at our schools soccer game. it was really cold that night and he gave me his hoodie. it was amazing there were fireworks at the game and right then and there I fell in love with him. the next day after the dance he asked me to be his girlfriend and I said yes. and it has been 6 months and we have done everything with eachother. he was my first for everything.. first makeout, first guy to see me naked, first guy to have oral sex with, and I lost my virginity to him. I love him deeply and I just want to do something for him that would just blow his mind when he gets back from vacation with his famiy in a few days. does anyone have suggestions?
