I’m just making an assumption here based on my experience and speaking generally about how these “masseurs” tend to behave. The massage often seems like an afterthought or more of an excuse that if they don’t find you attractive enough, they won’t go all the way. Instead, they stick to a subpar “massage” on the bed with baby oil and they deliver a mechanical HE, and end the session early. If they’re into you, then they take things further.
I remember a masseur that many guys here were raving about, but without sharing much detail. I traveled more than an hour to meet him, and it ended up being a huge disappointment. The massage lasted about 10 minutes on the bed before he wanted me to fuck him. I did, but I didn’t really enjoy it. I was looking for a sensual and erotic massage, not just a quick fuck session. And yes, the session ended right after I came.
