The issue of rapes, according to me, begins with the common misunderstanding that if you are adult/adolescent and have sexual urges, you require a girlfriend/boyfriend. The model is okay as far as you find one easily. But, it breaks down upon our failing to understand that sexual urges are born due to hormones which do not understand sexes—they are just mechanical and are set/bound to work if you’re perfectly healthy. So, our misinterprettation of this basic thing makes opposite sex an edible substance. Sexual urges are bound to be even if one is born and grows inside a box, completely oblivious of existence of an opposite sex! The release of oxitocin tries to take the matter further in its own hands by trying to trick the brain into liking other identifying attributes like voice, smell and touch. But, for civilized human beings such as ourselves, even this cannot be called love because it is not intentional… it’s just been happening because you are healthy.
A girlfriend/boyfriend is a human being first and cannot be treated as an edible. This thing is seen in those examples when people who are frequent to visit prostitutes finally find love. And hence it is quite funny how prostitution has built itself up and kept around for really really long now. Nobody wants to be a prostitute[or say a temporary substitute]. So, first of all, we require an education to be able to understand and tame the urges so as we do not make them a reason at all to have relationship in first place. Sadly enough, however, there have been generations now which have built the social structures based entirely upon accepting relationships as outlets, and not as co-inhabitance.
Conclusion: girlfriends/boyfriends are not an answer to sexual urges; presently, there is no answer to these urges except either taming them or simple letting your fluids out.
