The basic technique that I teach (at so-called female Self-defense classes) is a straight wrist grab (defense). This is produced (meaning set-up) by the tori (defender) by them placing their weak-side arm, horizontally across their body at face level, hand open, and palm-out. This serves several purposes, first, it places something between them(specifically their head/neck) and their aggressor (for interfering with in-coming strikes/slaps), second, it provides bait. By being in the way, an aggressor will be inclined to move it. That's accomplished by grabbing it (to do so), and very likely, holding it to keep it out of the way.
When the aggressor first grabs it, is when the tori (defender) should grasp it (to pin-it to their own arm), and apply the (tuite) technique, consisting of motioning the elbow of the held wrist's arm around and over the aggressor's wrist. This presuming the aggressor used the hand directly across from the held wrist(tori's left wrist, grabbed by aggressor's right hand).
If the aggressor were to grab cross-body (odd, but not impossible), the tori would (in the same motion as before) grab the aggressor's grabbing hand, and close their (previously) open-hand (to make a fist), which would then be motioned (again) over the top of that (grabbing) hand's wrist (both methods crossing over the ulnar side first, intending to bend the aggressor's grabbing wrist forward).
This (simplistic) application, of a (usually) ignored technique (as being considered previously impractical) is the very basis of what I'm attempting to convey. Women, will approach this technique (in this application/manner) with a more favorable attitude, than a male would. Though it would be more practical for a male to utilize this technique (as opposed to a striking alternative), they will commonly opt for the one which contains an impact in it's execution (which creates less damage, and is more difficult to implement).
Males will also tend to over-focus, on striking the face/head of an aggressor. Women rarely do so. Their difficulty/problem, is usually that they don't believe that (what-ever) strike/tuite technique that they're performing (be it anywhere else upon the body/arm's) is going to do anything (basically a self-confidence issue, unrelated to the technique itself).
