Will I confuse users by making my whole site HTTPS?

I'd like to make every page on my site load through HTTPS by default (less hassle at my end, personally I prefer HTTPS if given a choice as a user).

However, I'm concerned that seeing the HTTPS icon / green bar in their browser will confuse some users, because they associate it (and have even been told to associate it by many sites) with things like secure logins, online purchases, personal information being sent etc.

My site does have a members area, but also a lot of free content that anyone can access.

Question: is it likely that seeing HTTPS on simple content pages will confuse users, or make them wary that something 'more serious' is going on?
