Helix syn update, no progress and questions

Hey everyone, I don’t want to post everything again you can easily see my other posts through this account. Unfortunately my experience always devolves into me getting lazy, masturbating and I do then feel a bit of prostate “bumping?” I’m starting to believe the syn is not big enough, I have read the same for a few bigger people online. I’m kind of curious to have one of my trans friends give me anal (she is 6′ hard) since she is willing to help me with this.

Few questions

Hey everyone, I have a helix syn and have been experimenting with minimal results, I have done 2 “sessions”.. The second session I manually came a few times and noticed when I did I would have a pulsing feel deep in my hole near the end of the syn, was that my prostate? Also, I can’t find a precise answer but how do prostate / vaginal orgasms compare? People say they are similar and I am curious.
