Girls, i need some answers.?

Okay, well, ive been with my girlfriend for 5 months, and things are going great. I really want to be able to do more to make her feel absolutely amazing i dont care at all how i feel id rather make her feel perfect and special and do anything to please her. She goes CRAZY when i kiss her neck, and shes extremely ticklish on her sides, and prettymuch everywhere actually. Please let me know anything, i mean anything, that you have tried with your boyfriend, or guys, that you have done to your girlfriend, that was an absolutely amazingg feeling.
