I like it a lot. I call my boyfriend daddy and we have some aspects of DDLG in our every day relationship.
However, I'm more into having an assertive, loving caregiver than I am into age regression. I like having him take control, make decisions for me, and care for me. I don't really like diapers, or things like that and I don't go into "little space." So I guess I just dabble in it. I think it's a great coping mechanism for those who have suffered from trauma or have mental illnesses. (It helps me with my anxiety disorder)
