I'm 22, and my husband and I have sex maybe once every two-three weeks.  I just can't get wet or turned on anymore!  Don't get me wrong, I love sex, and I find him extremely sexy, but I just lose interest after like 2 minutes and start to go dry. It's horribly embarrassing, and Im afraid he feels like it's his fault that I can't stay wet, which it's 100% not. Our primary form of birth control is a condom, but I have decided to want to go on the pill. Which pill is known for increasing libido, and which ones  are known to decrease/keep it the same?
