Sex is a need the same a companionship and meaningful social interactions are. But not on par with basic human rights, as you are not allowed to superimpose your needs over others bodily autonomy thus harming them in the process.

Most individuals will experience sex with willing & caring partners. Only a very very small subset of the population will not. It would be a detriment to society if the laws were bent or changed to benefit such individuals. Laws are in place to uphold human rights for the good of society and because of this they benefit the majority not the few.

Nor should the laws be bent to punish those who willingly participate in such acts at the monetary cost of others (taxes that pay for our social security, sex Ed in school, access to contraceptives & abortions ect) as these things vastly benefit society far more than the money being spent on them is worth.
