How do I get a boyfriend?

So, I'm a sopre in high school and I've never had a boyfriend. My friends say that I'm too picky (sorry that I don't want to date suicidal guys, geez!) and I should lower my standards. My standards are: decent looking, nice, fairly smart, taller than me, and funny. Oh, and NOT SUICIDAL. I could date a guy thats suicidal, if I was really desperate, but I really don't want to. Anyways, do you think I should lower my standards? How can I get a boyfriend? How can I talk to guys? (I get really shy around them mostly..) Thanks in advance(:
