No worries. The "many months" was there to parallel the hesitation that we all have when revealing an important truth. It could be minutes, days, meetings, but the initial reluctance is there. Months may be excessive when it comes to a close relationship but a necessary exaggeration to illustrate the point.
The culinary profession was used to emphasize the similar nature of providing sensual experience, and how we can all have our emotions tied to it (both as the chef and as the diner). If we have done for business, what we now choose to do exclusively with a significant other, that is fact, and no amount of rationalization can remove that fact.
If we choose not to avoid it, the only contention is how that fact is perceived by your partner and yourself.
In the former, I would be OK with it. What someone has to do to make ends meet is all about survival. Rent has to be paid. That doesn't translate to license to be liberal in my own conduct (I'm a one-woman man and that woman would know it). I would be dedicated to performing so well, that she'd quit because there is just no better than her man at home.

Besides, I make enough to keep both of us warm, well-clothed, well automobiled, well vacationed, etc...
In the latter, it comes down to whether or not one has really been honest with themselves. If any emotions are tied up in it, then that's something that needs to be addressed. These are personal things of course so there is no need to divulge or defend. Just food for thought.
The truth about lies...
There's a big difference between being a habitual liar (aka "total liar") and being guarded. It's never black-and-white either. We often don't tell the truth to others not to hide it from them, but to hide it (and the perceived consequences of it's exposure) from ourselves. There are people who will never leave their home without makeup on. There are those who don't admit to taking rapid transit. I look at intent rather than transaction. We all learn to tell people what they want to hear to avoid conflict. Honesty comes with trust (or chemically induced means...)
