Methods of overcoming LMR besides the freezeout?

Several people here have mentioned using the freeze-out, but i feel that it's kinda immature and in a way "guilt-tripping" them into having sex. Basically i feel that this would ruin my chances at a second opportunity, or turning it into a fwb-relationship.

I did all the kino i could, i followed the kino ladder, got her into bed, we're cuddling and fondling and feeling each other up. underwear still on and she doesn't let me go any further, making excuses like she's tired or what not.

any tips/tricks out there? or if the freeze out is truly the best way to combat LMR, please convince me :)
