If you have a vulva, then trust me, make sure you try the sucking function! It can change your world! The combination of the beautiful vibrations and the sucking that simulates oral sex takes your senses in a different direction than normal sex.
Clitoral suction is one of the most effective ways to increase the intensity of your clitoral orgasm while still being able to have good penetrative sex with your partner. You may even find that your partner is having multiple orgasms in the process.
