Kaja Ah, the theory versus how it's practiced.
I think it strongly depends upon the country & society on one hand. There are (or were) certainly Muslim societies that are more relaxed. Metropolitan Turkey comes to mind.
It's also a question how the family and person handles their faith, there are certainly, especially in the West more than enough Muslims who are "social Muslims", not very religious. They might avoid obviously non-halal food, but won't make a bother out of it. Basically these are secular people, and if you don't know that they are Muslims, you would probably only notice by asking. Hard to distinguish from secular Jews or secular Christians.
(Offtopic historical rant: Germany pre WWII had a rather big population of secular Jews, that considered themselves Germans first, due to Germany being one of the first countries in the 19th century granting full citizenship rights to Jews, and these Nazi idiots ruined that national treasure for ideological reasons and because of their inferiority complex.)
Basically the same as most Christians nowadays, which are more "social" members of the Church (for the social benefits) than their soul.
But then there are religious nuts. There you'll find, cough, that all abrahamic religions have very similar views on chastity (especially female chastity in practice), masturbation, etc.
Actually, Muslims, in the actively religious nut variant might be more "liberated" than the Christian bible belt version, their holy texts seem not to limit married sex to procreation as at least some major Christian sects preach.
