I've been taking L-ARGININE for about a month now about 2000mg a day, and at first the effects were great. Rock hard erections, shorter "recovery" time between orgasims, etc. But now it takes me for-ev-er to cum. Sometimes I wont be able to at all or have to consintrate on "cumming" ver hard to be able to. Girl friend is getting pissed off because she can't make me cum! Help! Should i stop taking L-ARGININE or take more or what?
