Happy to help illuminate your understanding! It's fairly straightforward once it's explained. There are two parallel rationales:
First is consent. Second is the tantric practice itself.
Reason the First:
They consent to touching you in order to give you pleasure;
They do not consent to getting naked.
That's... fairly straightforward.
Like, a legit RMT consents to massaging you all over but obviously would kick you out if you asked
them to get topless. Right? Well, for
legit tantra massage providers, the only difference is they touch one extra part of your body. Your junk. Same deal. These aren't escorts looking to suck and fuck you
(bless those escorts, how I adore the work they do!) tantric massage providers are something else entirely: Tantric providers are willing to massage you with their hands into bliss. And that's it. Just because someone's willing to do
X doesn't mean it's weird to be unwilling to do
Y.
Reason the Second:
For many, tantra massage is a therapeutic and/or a spiritual practice. Asking to see titties demonstrates that you don't get it. Tantra is about connecting with your own body. Distracting yourself with titties means you're leaving the experience of your own body by concentrating on
their body instead of the experience they're working very hard to provide for you. By asking to see titty, you're rejecting the fundamental purpose of tantric massage. You're denying the intention of pure attention on your own mind/body connection by looking outwards instead of focusing inwards. You don't need to agree with their outlook but you can't deny it's a coherent philosophy and makes total sense within their spiritual paradigm.
Hope that helps!
It's perplexing how they have no problems doing what they're doing but asking about topless is what sets them off? I really don't understand haha.
