How Long Before you Felt Pleasure?

I have had my Aneros Helix Trident for a couple of months. I use it a couple of times a week and have little to no success in getting any pleasure. It doesn’t feel bad or uncomfortable, but I just can’t seem to get any pleasure.

How long did it take you before you started to feel any pleasure and how long into your session did it take? My sessions last for about an hour but I get discouraged any longer than that because I don’t feel anything.
