I tried Avlimil and I thought it seemed to increase a little but then again, I don't really have any libido problems, I was more curious than anything. It's not a pill like cialis or viagra where you take it and it works right away. Avlimil says you need to take it for a couple of months to really see any benefits. I had asked around on another board if anyone else had tried it and one of the guys said his wife was on it for 4 months and it had no effect on her at all. Avlimil is basically a bunch of herbs, no actual drugs in it.
Test. will definitely increase libido, so if your girl's libido is lacking, have her go to her GYN and they can prescribe a test. cream or gell. They may want to test her hormone levels too. If she's on birth control, that will often lower sex drive.
