Hi arose. This is an excellent and very common question. When we first started having intercourse, I too had to adjust to the movement aspect of things. What really helped us was practicing in advance of intercourse with the dilators. We used the largest blue pure romance dilator and would practice the same type of movements with this (i.e. taking it out and putting it in at varying speeds and also moving it around quite a bit). It may seem strange at first, but it worked really well and helped me to become much more comfortable with movement and to also trust him that much more. Hope this helps.
