I've had different therapists in the past and they all had different policies about out of session contact. Depending on your needs, you may want to bring that up as a question in the first session with any new t you are thinking about seeing. That way, you know up front if they are willing to provide you with the support you want and you don't find out later on when you're more emotionally invested in the relationship.

Only risk is, sometimes they tell you that out of session contact is ok and then at some point in the relationship they change their mind and tell you that they don't feel like doing that anymore or don't want to do that anymore or that it was wrong of them to do it in the first place. That has the potential to really really hurt.
