Confessions: At 28, I still secretly suck my thumb, should I tell my fiancée?

Now I do it secretly, especially in bed (Photo: Shutterstock)

I am 28 years old and a lab technician working in Nairobi. I have been sucking my thumb ever since I was a child. I have always been teased about it throughout my school years and also in our estate but I have never managed to quit. Now that I’m working, I do it secretly, especially in bed. I am now engaged and my fiancée doesn’t know about it. I don’t know how she will take it. Do I tell her about it or do I wait for her to find out for herself?
