Sometimes it happened to me like this: a girl with beautiful legs, and the rest is ugly. I felt like I was raped: I do not want her, but something forces me.
I am not a perfect man, I may be drawn to an unbelieving girl, but this is the same rape: unbelievers do not attract me. There is even almost nothing to talk about.
But if I do not want to be “raped”, then I am going to definitely marry a believing girl (by the way, I keep in mind an African student of 22 years).
So, do not “rape” yourself and try to fulfill the commandments artificially. Keep them in mind, but live as you see fit. Read the link above.
