1. My lack of stamina to hobby as frequently as my libido mandates
2. My lack of time.
None of which are providers problems, they are mine. I dont have any problems with the providers i see. i must be a very lucky guy. I dont have horror stories, and aside from the occasional tardiness (which i dont consider a provider problem, but womens nature - and i love women too much to let that bother me), i have no complaints.
Thank you ladies that i have been with. You know who you are and you are all awesome to me.
