I’ve found A4A to be quite useful. Have mainly hired for massage, but it was pretty clear from communications with the providers that many of them also offered a more...eh comprehensive service, shall we say? ? I like the fact that private/more revealing pics can be made available, as compared to the strict rules that masseurfinder enforce nowadays.
That is a very long winded way of saying: it is for both, but more discreet than rentmen if you are looking to escort.
As a side note, a recent phone number search took me to https://jock2go.eu/ and I was surprised by how much local talent was on there. Some profiles did appear to be stale, but quite a few new faces. ?
