What both of those other ladies said is spot on.
Get to know yourself. What YOU like and don't like. What turns you on faster. What hurts or doesn't feel right.
Don't be embarrased to try anything. Vibrators, toys. It might even be something as simple as using a little lube when you have sex. And your fanatsies are very sexy to your boyfriend. Trust me
Don't be afraid to express yourself. Wear some clothes that make you feel sexy. Watch a sexy movie or listen to music to put you in the mood. Eat some spicy foods first (habaneros peppers!!!)
You'll soon find what works for you and your partner and soon you'll be having mind blowing "couple sex"
