Diva Cup

Hi, I bought the Diva Cup a while ago and tried to use it when I first got it. However, when I did put it in successfully for the first time it went really high up and I freaked out a little. I calmed myself down and ended up getting it out but got scared to try it again. I know it won't get lost but, that fact doesn't make me any less scared of it going too high. Anyway, I decided to give it a try again even though I am still scared of it going too high. Do any of you happen to have any tips to help me be more relaxed when getting it out? P.s. I've heard of kegels but am not quite sure how to do it.
