I use Edge with my fwb. Put it on the night before, about 12 hrs, coz it lasts longer than that and by the time I'm seeing her in the morning the effect will have faded a little but just enough to be in that sweet spot - able to pound away for ages but still have some sensation. I still need to concentrate and hold back but it's easier than w/o Edge. I also take Cialis in the morn to help keep me up.
