Age does matter dude. Especially to the ladies. She will lie to your face as to not hurt your feelings probably because she does actually like you. But if I imagine the me of 15 and the me of 18. The 18 year old version would kick the crap out of the 15 year old one. Thats how different people become. So you guys are just at 2 different points in your life. But oh well. Everything at 15 seems like the end of the world. But if you can mack and get an 18 year old at 15 just keep at it and you will be a master pimp.
