I know it is late to respond. You may have found answer, but let me tell you something.

If you're somehow caught off guard and brought down, (and not knocked unconscious or badly incapacitated physically), even if your arms are pinned, remember for the guy to do anything next he's going to have to dedicate at least one arm towards that goal. No hesitation in disbelief. No halfway attempt at eye gouging thinking you just want to get free, but don't want to hurt someone, etc. etc. However strong or weak you may be, you just put everything into doing whatever possible damage you can with whatever body part it is you have free. Then run away screaming as fast as loud as you can. And don't clean up. Get to police / hospital where they'll get whatever DNA, etc. evidence they can off of you.

Hope it never happens.
