Penetration depth is kind of a Goldilocks issue — too deep and it's like he's challenging your cervix to a boxing match, too shallow and it's just kind of "meh." (If your dude is super long, you might be getting too much of the former, so feel free to step away from this article. You, my friend, will need "Positions if He Has a Big Penis"). When you can figure out ways to get it just right deep penetration can be so, so good.
For a whole new way of experiencing each other, get on your side, lift a leg up, and have him straddle your leg, entering from a kneeling position. He may find spots you didn't know you had, and if he doesn't, squirt a little dollop of lube on his fingers so he can cup his hand over your clit right deep into herlimit, giving you a long smooth rub with every thrust. Plus, if he is a man with a bit of a bend to his penis, this is a great way to embrace his curves. Get an even deeper feel by pushing your body back with your hands to take him in further or rotate your hips to play with the angle.
Give the wheelbarrow a try if you are up for a challenge and strong as hell. It's like the grade-school wheelbarrow game, but naked and with fucking. Assume the position, with your arms straight out to the floor, holding your weight (I told you this shit was hard) while your partner holds up your legs and enters standing from behind. If things get too crazy, or you just can't hold yourself up, lie facedown with your hips at the edge of the bed and let him lift up your legs to get you to dick-height. Best rec with this is trying the first version, just to have done it, but finishing in the second way, so you can give relax and give yourself some clit love.
