haha. Cross, take this example.
I am studying for a college exam and you walk in all upbeat and pumped up, that's annoying.
I am at a party and letting loose, and you come by me all serious and mature-acting, that's annoying.
Stop getting so offended, people don't dislike other people because they are annoying, annoying is just the word we use but what we really mean at that time is, "This is not the right time."
Be yourself, be sexual, get you a positive group of friends and enjoy life. Think about it, Ashton Kutcher is very annoying to people when he's punking them! But he's still Ashton, and that's why we like him! We like you too, don't change! Be sexual around women, be cool around guys, and you're cool with us.
