Can I read a book from a rabbi that is not a prayer in bed without a shirt?

Not sure if this is the place to ask this, but I’ve been having this dilemma/internal question for a while now.

I’m Jewish that keep many things and am trying to learn and get better. In doing so, I bought a few books about judaism that are not prayers, but rather teach about Judaism and halachot. For example: – Judaism – life changing ideas by Rabbi Jonathan Sacks. – Jewish literacy by rabbi Joseph telushkin

The question – i do my reading mostly at night before I go to sleep, in my bed and without a shirt, and with my fiancé next to me. Because of that, I barely read the books above because the dilemma and question I have is – is it ok to read such books that were written by rabbis, in bed and without clothes and with a women that is not my wife yet next to me?

Appreciate any insight and feedback on this from people that may know the answer. Thanks!
