“You can masturbate standing up in the kitchen, lying in the bath, be experimental,” says Reed Amber, the other half of Come Curious. Don't masturbate like it's something you have to accomplish or else.
If you only have five minutes or you've set aside a day like you need to get this figured out, odds are you'e going to be way too stressed to allow the kind of no-pressure chill vibe you should ideally have when you're masturbating, at least in the beginning. Mc Combs recommends putting a quarter-size amount of lube onto your index and middle fingers and gently massaging it around your clitoris (the little button-shaped thing at the top of your vagina) and inner labia (the folds inside the larger folds that make up most of your vagina).
So shut your phone, put on some music that turns you on, and take your time. Sure, you might have enough natural vaginal lubrication to start with, but if you don't, extra lube (no matter where it comes from) will make it a lot more comfortable. You don't have to focus on the vagina and nothing but the vagina.
It's just a good starting point to get some blood flowing down there, which helps increase pleasure and arousal.
Plus, you're getting a feel for what you like and you can always keep repeating whatever is working for you from there. You can use a vibrator, but you shouldn't necessarily start with that.
Masturbation (or masty time, if you will) is a great way to unwind, treat yourself, learn more about your sexuality, and yes, improve your sex life, in general.
