I use kratom a lot. I take doses between 14-40 grams at a time. I don't us it every day, I use it on average 12 times a month. I use powdered Bali and it works very well for me, but I have noticed that every time I do it I have an erection for hours on end. It's not that I'm thinking sexually, or excited. I just get an erection and it won't go away. It's not a rock-hard, super erection that you would expect from viagra or something, but an erection nonetheless. Can anyone else relate to this, or possibly explain the mechanism of action? Why am I getting erections from kratom? It also makes me itch more than normal opioids.
