>You can see it on TV. Take DareDevils TVSeries, but I'm sure you'll find many examples, there are countless raw violence scenes for free, but 3 seasons in and DareDevil hasn't been with a woman with the exception of a kiss.
Or perhaps that has more to do with the fact that Catholicism is central to Mathew Murdock as a character, so it makes sense he isn't sleeping around given that premarital sex is a big no-no for Catholics. Also, we're only two seasons in, not three.
