It is normal. I myself am not comfortable lol but I never force my couples to do anything that makes them uncomfortable. Typically I talk and joke a lot with my couples in order to relax them and bring out their natural chemistry and bond as we shoot. it's never an awkward shoot. I do my best to make it fun and memorable for them.
Yes. I provide services for both. I like to consider myself a "Hybrid Shooter" not many artists out there have mastered both arts of photography and video.
