If you’re genuinely interested in learning the second language, then I would say yes. Before I started working in the adult industry, I worked in a cell phone store (on commission) that had a large Spanish-speaking clientele. Since no one else in the store was bilingual, I decided to learn enough Spanish to tell them about what we had, how our service worked, etc. After I started communicating with them and word spread through the community, my commission went through the roof! However, I never would have been able to learn the language if I didn’t have a genuine interest in it to begin with.
