Is there any way I can get him to kiss me?

I never really liked kissing before because my first boyfriend (Some jerk) was all slobbery and horny, but my second boyfriend showed me how much fun it could be. We broke up but we're still friends. Meanwhile, I was receiving strange but beautiful love letters and flowers and chocolates, and soon my best friend Juan Lopez, the cl Brainiac and a studious goody-two-shoes, invited me to dinner at his house. He admitted to writing the love poems and bought me gorgeous earrings after the lovely dinner. How could I say no? However, Juan, being the cl brainiac, is way too strict at times. I keep trying to kiss him but he looks frightened and worried, and I tell him it's no big deal but he acts like he doesn't know what I'm talking about. I am his first real girlfriend, and it's understandable that he's shy, but every time I try to kiss him he gets nervous, even sometimes a simple flirt sends him into paranoia. I know he is a perfectionist, so he is probably aiming for the perfect time and place and stuff like that, and he is also very timid, so likewise he is frightened. What can i do so he'll kiss me?
