A right of passage related to sex and violence.
First to explain a right of passage is not only something that one does to symbolically transition from (boy to man) it is really any activity or action that signifies a transition from one state to another. It traditionally is explained with three stages separation (often a feeling of not belonging to or wanting not to belong to groupX), liminality (limbo or risk), and re-incorporation or re-integration (acceptance of or being accepted into). It is endemic to all social structures with hierarchies or in other words it's in almost everything we do as social beings. It happens during the "promotion" ritual at work transitioning from one position to another.
It happens when a person asks his/her partner to marry. It happens during a disagreement with a superior. All these things have built in social rules/frames/moraes that when breached have real consequences. Some rights of passage are framed biologically, others not so much, but what is common about them all is the structured transition and attitudes and emotions one is expected to feel and the manners in which others involved in that particular cultural group treat the passenger before and after the right of passage is complete.
Sex: Condoms handed out at school, correct; in no way is that forcing a kid to have sex. The claim was not that kids are forced to do anything. The claim was that sanctioning birth control has the same effect as sanctioning violence, in that "if the kids are going to do them anyway, we might as well limit the dangers as much as possible". Yet sex is a perfect example of a right of passage from boy to man. Take the movie The 40 Year Old Virgin for example, the reason why it is so comedic is because that man is not yet a "man". The age of loss of virginity for both sexes in different ways is directly tied socio-culturally with their status in a group. The frequency of sex and or number of sexual partners is as well. Types of sex acts in certain cultures also are right of passage. In a BS&M circle the difference between vanilla and non-vanilla sex acts is the difference between transitioning from out of the group to into the group. It goes on.
Violence: much the same as in sex transitioning from boy to man or from group to group, or hierarchical level of prestige to the next can be wrapped up in willingness to commit or receive violence. Some things are formal like being Jumped Into a gang, others not so much like being a schoolyard tough. If a person has really observed schoolyard fight they will have noticed that there is a well-versed play in which the parties are all but quoting lines. Sports are structured sanctioned violence or violence proxies that serve the right of passage function for young men, but since they are sanctioned and like condoms being handed out in Sex Ed (limiting the danger), they are praised.
In all these examples someone is transitioning from one level of a social/cultural hierarchy to another, in all of them one has the desire to leave or is being forced out of a hierarchical level, often an action that involves personal risk to body, image, or psyche is committed, then that person upon successful commission of that act is integrated into the other level. All of these have specified and pre-agreed upon structures for the parties involved, although often the parties are not aware of their own roles in them. All of them have very real consequences. I am not saying that everything must be a right of passage because life is always transitional; however those things that after having experienced one looks back and says, "hey that choice shaped my life in (X) way" could certainly be considered as such.
