I finally got an involuntary contraction, but stuck here. help!

I am a beginner and I need help to break through wherever I get stuck. please help and thanks in advance.

– Before this session, I stopped jerking off for about 6-7 days. But I gave enough edging and stimulation so I can be horny while waiting.

– Did full enema. (took about 2 hours)

– I took edible 35 mg after a small dinner.

– Waterbased lube was injected

– Started with a finger and small dildo to stimulate the prostate. I was switching between MGX, Helix, and ProgasmJr to find what feels better. And I figured MGX hit the spot so I was using MGX for the rest of the session.

– And I stimulated my nipples (I think they are linked to my prostate?) and felt tingles around my prostate. Whenever I touched my nipples I felt a little bit of contraction and it led to an involuntary, also a little bit of spasm. I did not know what it was but I just let it happen. When it happens, my PC muscles got contracted and my abs got spasmed. Looks like my body almost did crunch when it happened.

I felt tingles and was able to do involuntary contractions, but it was not going anywhere from here.

Am I doing this right?

Should I try to be more relaxed when it contracts?

Maybe I felt numb because I took edible too much?

I am a beginner, I need some advice

I bought prostate massager https://www.amazon.com/dp/B08C4Y165X?ref=ppx_pop_mob_ap_share from amazon last week and started to use it.

I had only 4 sessions so far.

First session was all about how to use the toy and feel it in my anal. After first session, I started to get some infos from here.

Next day, second session, I took edible (25mg works best for me), used douche and rinse it around 3-4 times and took hot shower. After couple hours, it started to kick in and I got really relaxed. I injected anal lube and used my finger. It felt good even just rubbing it with my finger. And I inserted my toy and started to find prostate. It took a while but I was able to find it. It was tickling at the beginning, so I just let it tickles. This feeling was gradually getting bigger and it felt totally different than stroking dick and cum. It was amazing.

I rest one day and tried again next two days. One with edible and one without it. During these two sessions, I was not able to even get to “tickling” part.

Am I doing this too often? Maybe prostate needs a rest after one or two sessions?

Thank you in advance for your advice.
