I have tried the the Intimate Organics Intense and it works. It was not as dramatic as I had hoped but I could definitely tell a difference. While looking for a link for you I discovered this has been discontinued. I am so sad! This was the only L-arginine gel I had found that was paraben and glycerine free.
In my search I see some that come highly recomended that have parabens and glycerine. These are the ones I wish I could try.
Shunga Secret Garden,
Shunga Rain of Love, and it seems like there were others that I can't find this morning. I actually did try
Durex Utopia and it does work well but I did have an allergic reaction to it that lasted 2 1/2 days. If you aren't allergic to parabens like I am give one of those a try. If you do find a paraben free stim gel please let me know!
And hi, I don't think I've seen you around before now.
