The thing is, if you're only loveually active with one (straight) partner, you don't have to wear a condom unless you don't want to have babies because STIs are very uncommon if you're both only active with each other.
With brown town love, you always have to wear protection regardless how long you have known eachother because there is a considerably higher risk of getting any sort of STI due to faeces. This is because star fish is not supposed to be penetrated.
Not to mention it completely destroys your star fish but that's the least of problems
