Well, then you did not learn the Haluches. Or if your LOR told you so, then HE did not learn.
Why do people think that Yiddishkeit/Halacha is about auto-responses? If it were that way we wouldn't need Rabbonim, Moirei Horo'o, and for that matter we could probably eliminate 90% of Halacha Seforim.
The psak that I heard several times is that as long as it's not לתענוג but something that you would do any other day of the year, it's a non-issue (frequency, temp, etc). The halachos about bathing in the 9 days were written in a different time and place, when bathing was a luxury and wasn't a daily routine (nor was hot, or for that matter running water).
