Yes, I believe learning some basic groundfighting will help you if you're ever in a rape situation. First of all, I have little faith in techniques such as eyegouges, in particular. Even strikes in general are pretty ineffective when done from a bottom position. I'm not intimately familiar with rapists, but having grappled with buddies who have no skill, the first thing they all do is try to control my arms, when I've got them in closed guard. I assume a rapist would do much the same, presuming he's already spread your legs and gotten between them (which is essentially the guard position in submission wrestling). From guard you have a variety of moves you can perform, but in this case I'd specifically advocate teaching the armbar. http://bjj.org/techniques/bjjfighter/gi/guard/armbar/ As you can see, if he happens to be stretching your arms up over your head, he's already given you his arm for free. Shoot your hips and break it. Acidrain - You claim BJJ isn't brutal enough. Personally, I don't think you've trained it at all. Very few submissions are based on pain. They will either break your joints, or choke you to unconciousness (shortly followed by death). There's obviously a lot of sweeps and submissions you can perform from various forms of the guard, but I don't see a point in going over the top for a short rape prevention seminar, or something such as that. Case in point, having some basic submission wrestling skills will be very useful a rape attempt ever gets as far as you ending up on the ground.
