At the moment, we have the stealth_sex tag, which is an umbrella tag for any sex act discreetly done in the presence of people, and we have various stealth_X tags for sex acts, but we don't have any stealth_X tags that imply the stealth_sex umbrella tag, so we should imply (or maybe alias) all the stealth_X sex act tags to stealth_sex.
I've made two BURs (one for the imply option and the other for the alias option)
Also, the only stealth_X tag that implies X is stealth_masturbation so both BURs have a solution for that too.
