Any tips for a beginner? My sessions tend to end in hands free orgasm...

Sounds really good! That’s kinda how I started off with a hfwo. What model are you using for your sessions and how long are they? I use the helix Syn which has given me a few dry o’s. I would suggest you to lie on your back with your feet spread apart and enjoy what is coming at you. Your body may shake like crazy but just enjoy it. Focus on pushing the aneros back and fourth in your ass. Eventually you will start to get dry o’s and minis like I do. It’s still pretty amazing that you get these feelings even though you cum at the end. Best of luck

I hope someone might have a helpful suggestion when it comes to being able to get beyond ejaculation. My sessions are always fun and vary quite a bit but, the real intense ones always end with me on all fours bucking, humping and cum blasting.

Ejaculations do generally have a trigger point that once tripped sets in motion a hormonal cascade which usually ends the orgasm, induces a refractory period and diminishes arousal. As @bigsnake30 mentioned you might try some different positions, a small change might be all you need to avoid unwanted ejaculation. I've been on this journey for over twelve years and I haven't experienced a HFWO, though I have experienced some minor spontaneous prostate milkings on occasion. There have been numerous reports of spontaneous ejaculatory orgasms during an Anerosession. Depending on your desire and point of view this could be a blessing or a curse. These threads, How to avoid ejaculation?], How to avoid handsfree wet orgasms & Avoiding ejaculation during orgasm?, exemplify the situation as a curse.

On the other hand, some men have been striving to bring about a HFWO with their Aneros in situ (please see Just can't achieve a "hands free" orgasm, Finally a hands-free orgasm! & Achieving hands-free ejaculation...continued). For these men the ability to have their HFWO's is a blessing.

Blessing or curse, it all depends on your attitude and intent but you can probably achieve your desired outcome through continued practice and mental focus.

If I was able to "move past" that hump would I be in the super O zone?

Perhaps... but understand that orgasms exist along a continuum of intensity and there is no real edge or "hump" to move past, you just transition up or down the continuum. Please see Super-O Myths & Illusions regarding 'the Edge' and a couple of other myths.
Also please read @neros thread The Myth of Super Orgasm.
Good Vibes to You !

WOW! Thanks gents for taking the time to respond! I have two models helix trident and a prograsm. The model I use the most is the Helix, as it hits all those special places. I will be trying a different position next session. My experience on my "back" the times I have tried really did not give me the desired results, I will employ more patience! Thanks for all the article suggestions I will be sure to pour through them for some great ideas. I'm so glad I started this journey, as a gay guy that loves getting f*cked... the Aneros toy has open a whole new dimension to my sexuality. I respond to my man in a different way and he FEELS me growing closer and opening up to his body, our connection is blossoming.
