I haven't lied to get laid but I'll post some of the lies I've heard other guys use. Some of my friends would say just about anything to get in a girl's pants through high school and college.
- "I'm rich"
- "I have a 9 inch *penis*"
- "I don't have a girlfriend"
- "Of course, I love you!"
- "Yes I want more than just sex from you"
- *some made up story showing what a bad-ass he is* <--- I was amazed how often this works
- "No, I don't sleep around"
- "You are special to me"
- "It'll be more than just one night"
