It definitely falls into the 'mileage may vary' category. Massage, unlike escorting, doesn't include oral services. I always see it as an extra extra (HE is extra) and it really depends on the chemistry between the two of you. I can't imagine a masseur providing BJ to every single client he has. So even if I recommend a masseur who does that to me, there's no guarantee he will do the same to you.
