internal vs. external prostate stimulation

[SteveSW]

Internal prostate stimulation, at least for me drives me to explosive orgasms that far surpass those from fucking, a blow job or masturbating. I have had mind bending orgasms from digital manipulation, and never touched my dick. It feels like no other sexual act, at least for me. I have vibrating or rotating insertables which I sometimes use when masturbating. They are effective, but for some reason a finger does it best for me. External pressure or massage on the perinium, while pleasurable, does very little for me.

I still vividly remember masturbating as a teenager one day and as I was about to come I pressed hard with a finger on my perinium. I don't know why I did this, it was just a lucky random move I guess, but I had the most intense, mind blowing orgasm I had ever experienced.

Yes it can make for a real intense squirt. But nobody teaches this or talks about it. In sex ed nobody ever said anything about the perineum. So is this like cheating or rushing to orgasm?

In my day, Sex Ed did not exist and for many years after, there was absolutely no reference to the pleasure aspects of sex, but only procreation and STDs. I suppose, depending on what school district, the curriculum will vary widely.

I appreciate your comment, but still wondering why one way works better than another. Both targeting the same area, yet it would seem our prostates are like one sided. You like side on the inside, and I seem to like the outer side? Why wouldn't we have equal sensations on all surfaces of the prostate?

All I can tell you is that I enjoy having my perinium pressed on, sucked on and stroked, that activity even using a vibrator just doesn't provide enough stimulation directly to my prostate to intensify my orgasm. I think in my case, there is too much tissue isolating my gland, which isn't true in your case.

(edited for focus)
I have often wondered why I can't seem to enjoy internal stimulation or find pleasure in it the same way I do the external way. What would cause this?

A person's skin is loaded with nerve endings which vary in density all over the body and even varies from person to person. Also, psychological aspects of stimulation (especially location on the body and context of the contact) will make a difference to how you feel about the activity.

My girlfriend loves to have her back scratched. I don't. I like a light, feather touch. By the same token one man might like a heavy touch on his perineum and another, a light touch. Some men might respond to pressure on the prostate from the inside and another might like stroking better. Also, one can "teach" one's nerve endings to like being stimulated in certain manners (that is, by repeated stimulation in a good context, a pseudo-pavlovian response of pleasure can be developed).

As for me, my perineum and scrotum have become more responsive/pleasurable over time as my currend girlfriend enjoys stroking me there (more than previous lovers have, so has generated a more intense response from me as she has done it over the past couple of years). My GF and I are experimenting with prostate massage to induce a "P-gasm" for me. I think we succeeded once and I look forward to more experimentation. But the P-gasm has proved elusive so far. I have done this with women to induce a G-spot orgasm, which for some women must be "learned" and for many is elusive as well. Technigue of the touch (stroking, pressure, speed, etc) must be practiced diligently.

So, to answer your question "what would cause this" (difference in pleasure); all the details and peripheral psychological, physical and emotional factors will make differences. The good news is that many of the factors that affect your response can be influenced or changed by practice (on the part of your lover and on the part of yourself, too).

I inserted three prostate vibrators with a diameter of 10mm and a length of 8 cm through the urethra into the prostate. The result is disappointing, unfortunately the vibration strength is not enough for me to trigger an orgasm. I use a Hegar dilator so I can get the vibrator into the prostate or bladder. I now leave the dilator in the urethra so that the vibrators do not wander out. Unfortunately, the vibration is not enough for me to ejaculate. But experimenting is still fun. If I manage to have an orgasm with additional masturbation, the ejaculate can easily flow past the vibrators because my urethra is stretched to 13mm.
