We rarely get that low in the summer, most of the time the dp is around 16-18c with periods where it goes up to 22-23c, and drier periods where it's like 10-13c.
But is it true that when heat is very humid (dew point over 75°F), it's like to breathe water vapor when you go outside ? Or that's a bit exaggerated ?

A bit exaggerated. You really start to feel breathing water vapour when dew point exceeds 29°C (84°F) which is rare in most of the world but unfortunately very common in my area. Also, you should come out of a cool place so you have cold nostrils and humid air starts condensing inside your nostrils. When you stay outside for more than 20 minutes your nose becomes warmer than the dew point and feeling of breathing water vapour stops.

I've experienced 80°F dewpoints in the deep south and even Missouri believe it or not, and it almost felt like you were drinking the air when you breathed. No thanks

Each year I experience at least 62 days of dewpoints above 26.6°C (80°F). Only when dew points exceed 29°C (84.2°) and I come from an air-conditioned place I feel that I am breathing water vapour.

It wont bother me for my sake, I would love to experience this sensation (feel like a vapor sauna/hammam) ! Constant sweat is the only true annoying thing in very humid heat though it is proven than sweat is very good for the skin and organism.

I don’t like to too dry or humid, but I’d go for a mix of both where the humid days are at least 10-15 F cooler than the dry days. The hottest day of the year needs to be one with dry heat, not humid heat.
How you know the difference between dry heat and humid heat without knowing the dew point, just by feeling ?
What’s the sensation when the temperature is 36°C with a 24°C dew point and 38°C with a 5°C dew point ?
One feels the humidity and may get beads of perspiration on various parts of the body. One usually can tolerate higher temperatures in dry heat and one does needs to drink even if one doesn't feel thirsty (as one doesn't feel the loss of liquid as much as in humid heat).
