In my culture many women have no idea of sex prior to marriage. Even if they marry by their own free volition, do they have the capacity to consent to sex for the first time given their lack of knowledge of the act?

I live in Bangladesh which has a highly conservative culture and society. It seems some women have no idea of sex prior to entering into marriage. 

From my understanding, the more of the society is that, at a minimum women and men must be walled off from each other. THere should be only civil communication and no one should have any sexual fantasies, no one should ever look at the opposite sex sexually, there should be no romantic or sexual feelings---anything more "vulgar" is unacceptable. People might deviate from the above transgressions but then they must repent. 

The general biology textbooks in Bengali medium seems to only talk about chromosomes and nothing else. No description of the act and not even those "coitus" and "genital" diagrams, available in GCSE textbooks most likely. 

There seems to be a number of women who never know what the deed looks like. I can't find the article now but I remember some news articles confirming this. 

However, most women today do have boyfriends and even though they get into an arranged marriage, the arranged marriages are not forced and they choose voluntarily. 

Assuming a situation where a woman (or even a man) who has no prior idea of what coitus looks like (but does marry someone on her own free consent)---does she or he have the capacity to consent to sex from an ethical/moral philosophical point of view because of the lack of knowledge?

I doubt there's anyone who really has *no idea* what sex is. Bangladesh is fairly rural; surely they could've observed sex in domestic or stray animals? Aren't there urban monkeys there? 

I imagine most poor people live in small homes, they could've been exposed to sex through their parents. In medieval Europe, many peasants lived in single-room homes, and there was no particular effort made to hide sex from children, who may have been in the same room or even the same bed.

There's also a good argument that people have biologically inherited knowledge of sex, even if they were never taught about it conceptually. Two sufficiently interested partners with no idea what sex is would still figure it out. Every living organism has primal, evolutionary drives of the *four Fs*: fighting, fleeing, feeding, and reproduction.
