Moaning Way vs Numbing Way

Unfortunately, despite owning 2 Aneros toys for several years I used them on and off. Mostly lack of privacy.

I restarted about 2 months ago, and I noticed something interesting. I feel two distinct kinds of pleasure depending on my position.

In most positions, especially on my back, Aneros rubs against different sides of my anus. It is very enjoyable and makes me moan a lot. I feel waves of pleasure and I need to adjust my position a bit every now and then to keep it.

In froggy position, aneros hitting me doesn't cause me to moan. Rather, it makes me pant, touch myself, push my head against bed. The feeling numbs my head and my penis. Penis becomes slightly engorged and slightly retracts inside body. It starts dripping some kind of clear fluid.

Does anyone feel like that ? Which way should I pursue ? I'm leaning towards the second, because it feels stronger and makes me lose control more. The first way is, I don't know, more exciting in a way, while the second is more like some stupor / torpor, but very nice. It calms me down.
