Any of those.
Laying on your side generally gives the most access. On your back can work but depends on how your belly lays while on your back.
Lifting your belly is an option but how well it works depends on how fast you get off. Lifting your belly isn't great it takes you a while.

I've definitely tried resting my belly on the counter, but unless you've got a serious apron belly you're too close to the counter to get much additional access.

Lol, yeah I'm right there with you. It's been years since I could see it over my belly and my fupa is fat enough to hide it completely.

I've had this a few times.
When I worked for McDonald's this got me out of mopping the lobby because the door to the cleaning closet was too narrow for me to be able to reach the faucet to fill the mop bucket.

This is one of the reasons I don't fly. I can squeeze into the bathroom on board but can't turn around once I'm in there. You know you're fat when you have to back into the bathroom on a plane.

At my favorite local cinema I've recently had to start using the handicap stall because my hips are too wide for the door on the normal stall and I don't fit sideways either.

Normal doors aren't a problem... Yet.

I got one of these last weekend.
I was at a convention and ran into a girl I knew in middle school, I've doubled my weight since she saw me last. She only recognized me by name. At least I wasn't the only one who had filled out.

Then I must be a saint.

Conversion therapy is something to be avoided but it is mainly used to try to turn gay people straight. It mostly turns gay people suicidal. I'd make an effort to avoid it but unless you're also gay I doubt it would even be considered, and if it is I'd find a new doctor.
