Many SPs who list it as a service may not be bothered to enjoy it and their faking is blatant so it's no benefit to the experience.
Still pretty easy to find girls who do appreciate a bit of attention down there or fake it well that it improves the vibe if not materially improves the performance of the services paid for, which is all most of us can hope for.
With those girls I've met who genuinely enjoy receiving it has certainly led to a lot of enhanced encounters with much increased and genuine engagement, a more uninhibited gfe/pse service and sometimes extras either on or off menu initiated gratis; mostly level and amount of kissing, gagging on cock, dt, anal, dp, heavying fingering front and back, fisting, cim, wanting to proceed to round n+1, squirting, extra time they did not ask payment for, and yes sometimes raw, risky slides and attempts to bb. No different to the best, involved civvy sex with a girl who enjoys getting a bit wild. Sure there are S tier SPs who provide this level of engagement consistently for their typically premium asking price. Unlocking this from less well-regarded or unknown SPs just gets you more good options more often or on a tighter budget.
If you enjoy giving oral to women then there is undeniable benefit to your punting beyond just licking whatever you can afford; whether it's overlooked matrons (well) passed their physical prime or gnds who might otherwise give you the time of day or girls clearly much better looking than you who garner plenty of attention from blokes who throw a lot more cash about.
