I have found three moves that work pretty well with guys. It's hard to describe in writing but I'll try. 1) While facing him I get my right arm around his neck and grab his right wrist with my left hand and push him down. I straddle him with my right leg, hooking his left leg and putting all my weight on him while squeezing him with that right arm. I try to keep his left arm bent and close in so he can't really apply his strength to well. If I've done it really well I have his jaw shoved down into my right armpit and he gets scared pretty quick and starts begging for mercy. 2) Another good one is if I can get on top of him, maybe playing that I am being sensual, and then wrap my legs around the outside of his, and then back underneath him so that my feet are hooked onto the front of his lower legs. At the same time I try to grab his wrists and push them down. When I stretch my legs it gives me a lot of leverage and if I do it right I can hold him down even if he's a lot stronger than me. I think this might be called a grapevine. 3) the old standby is to get him in a scissors hold around the middle and squeez the air out of him. With practice this gets easier. Most guys aren't really that tough. You go girl and put him in his place!

1) if he's ticklish, tickle him! Keep poking him until he either gives up or weakens enough to let you climb on top of him. Remember to keep tickling his weak spots to wear him down or he will probably throw you off.
2) girl's legs are pretty strong so if you can scissor him, you can win! Try to manuever yourself so that your legs are around his waist and start squeezing. He will give up in no time.
