Inspired by this question Can slave woman show herself to her master? and although freeing a slave is better(Qur'an 90:13), we all know that slavery is allowed in Islam. And this could be one of the reasons of so many rapes going on by Muslims(I feel). And from Is a woman required to have sex with her husband whenever he requests it?, we get an answer "Yes that's true. But men shouldn't take it literally. There must be kindness and understanding. Islam ordered the husband to be nice and gentle and understanding."
So, here are my questions,
1. Is forced slavery allowed in Islam?
2. Is forced sex with slaves allowed in Islam?
In the first question, I believe that, we should enslave women only from wars and not just go cherry pick a woman(non Muslim) you like from your region and enslave her, what if the woman/girl(after war) being enslaved refuses to be enslaved? and hence the question Is forced slavery allowed in Islam?
Next, now if the woman/girl agrees to be enslaved but what if she refuses to have sex with the master at all and hence the question Is forced sex with slaves allowed in Islam?.
Answers expected from all views supporting claims with authentic Hadith and verses of Qur'an.
Instead of asking in two separate questions, I asked very closely related questions at one place which had closely related small answers
