If the points are very low, the photoshoot will not progress beyond a point.If think go far during the photo shoot, hope he can stop think he dislike otherwise it would make sense in love path (0 corruption,voyeur,exib...)
Also for the love path my recommendation would be to collect some of these points here and there because otherwise some scenes will be locked later. Just for arguments sake let's say there is a h scene between fmc and mc in the office when no body is there. Logically I think they would at least need a few exhib, voyuer points before they will try something like that. It is difficult to add different fetishes (even if only between fmc and mc) if all points are always zero.
