There is a definite risk of neck-breaking here. You really don't want to have to be concentrating on things like keeping this position nonfatal while in the heat of passion.

2

Unless this is a position for anal sex, I don't quite see how this would work. Also, this is definitely how you get a penile fracture; penises are not supposed to bend down like that when erect.

3

This one doesn't look like that impossible of a pose, but it does seem like thrusting from this position would cause a lot of painful pelvic bruising for both parties.

4

The Kama Sutra should really be sorted into two categories: sex positions for acrobats and sex positions for regular people. I'm sure this position is wonderful for the people with the upper body strength to pull it off.

5

This is just horrible for everyone involved. From the person who has to point their penis down and somehow thrust simultaneously in to the person who has to break their neck to keep their nether regions skyward, this just has "penile fracture" and "neck fracture" written all over it.

6

The plough (or plow, based on where you live) seems to be a reasonable middle-ground between insane, impossible pose and actual fun sex position. Just make sure that whatever the person on the bottom is holding themselves up on is sturdy while you're plowing them.

7

The main problem with this position is thrusting. Neither person is in a good position to thrust, with the person on top having no leverage and the person on the bottom pinned down by the person on top. And what's sex without thrusting? Awkward, that's what.

8

No, that's not just missionary position; the person on the bottom's legs are closed. This is one of those positions that makes things tighter, and therefore heightens sensation. The only problem is that closing the legs makes it difficult to stay in or get back in there if things slip out. There are better closed legs positions out there.

Now that we're getting into the more possible, actually fun looking positions, I bet you've done it this way before and had no idea what it was called. Raising the leg like that allows for deeper penetration and more intense feelings; the fact that you're face to face with your partner while experiencing it is just a bonus.

10

Many of the Kama Sutra positions feel like only one person has to do a lot of work for the other's enjoyment, but this is one that actually seems like it'd be fun for all. Crossing the legs like that makes things tighter, heightening feeling for both parties.

This position is more commonly known as "reverse cowgirl," and it's a classic for a reason. Some think it's just to give the person on the bottom a great view of the person on top's bottom, but the way a penis is curved gives entirely new sensations when mounted backwards. Essentially, it's great for everyone!

12

Of course, if you're wearing socks during sex (which is actually a good idea). Similar to the splitting bamboo, this position is great for achieving deep penetration. Where it's different is that the person on top does all the work in this one, while they straddle their cross-legged partner.

13

This is just one of those really sweet positions. Cuddle sex is great for fostering intimacy in a relationship. Just remember if the little spoon has long hair, put it up in a bun, or the person in the back will be getting a face full of hair. Also, it gives them access to the little spoon's neck for kisses or nibbles, which make everything better.

14

Nope, this still isn't missionary! In this one, the person on top gets on all fours (or planks if they're really hardcore) while the person on the bottom lifts their hips and does all the thrusting.

15

This really is the perfect position: standing allows the thruster more control over how hard or soft they thrust, sitting on a table allows comfort for the person on the bottom, wrapping their legs around the thruster allows for deeper penetration which leads to heightened sensations and, best of all, this position allows both partners to be face to face while feeling all those simultaneous sensations. It can be fast and hard or slow and soft, and that makes it a winner.
