The Nirvana position is a change up on the missionary position. It's a little bit kinky, a little bit cheeky, and very fun!
The woman lies on the bottom, but rather than opening her legs up to receive her partner, she keeps her legs together - it makes it harder for her man to penetrate her, and when he does, it adds sensation by squeeezzzzzzinnngg around his cock.
For him, this adds more sensation and the mild kink factor of having to "work for it"! For her, this position is one that hits the G-spot and the clit.
Definitely try this position somewhere where you have space to reach above your head to leverage yourself off something solid - bedheads, walls, the um.... tea towel rail in the kitchen 😉
