The definition of GFE and PSE is pretty loose.
I’ve only seen a couple of providers that would fall into the PSE category as it’s not something I find very often where I live. But the high energy, “slutty/dirty mistress fantasy” and feeling my partner is uninhibited definitely gets me going even with a pretty vanilla list of acronyms.
What really makes me want to repeat is a feeling of mutual chemistry (may not be real) in bed and personality-wise, a good kisser and above all else great oral (receiving , and someone who enjoys my tongue).
For me a great bj is a sensual, teasing cock worshipping style bj, DT, BLS, licking, eye contact and feeling like she enjoys slowly devouring me. (Not high speed head bobbing). Now the real question is: is this type of bj GFE or PSE? Could be either or both, hah.
