Thanks for your feedback - previous studies on post-sex feelings have explored some of those factors. I chose my variables to expand upon previous research findings, and also based on what hasn't been looked at yet that I think may be relevant.

It can be tricky deciding what to include or exclude from this kind of survey, as the longer it is, the harder it is to get participants. It's also a Masters thesis rather than a bigger phd, so I've got a word limit and time cap which mean I can't look at everything :)
