Well now, that
is a different "kettle of fish"!
There are a lot of matters to address here. Clearly you have limited dexterity and power; I am wondering whether your inability to "masturbate normally" is basically due to inability to develop enough
pressure and
speed to effectively stroke your foreskin with your hand(s).
"Humping" the bed presumably provides more pressure (though not as much speed as you have to move your whole body), particularly on the underneath of the glans, which tends to be the most sensitive part. Presumably, actual intercourse restricts the amount of force you can apply (with comfort, to your girlfriend) and gives a different focus to the pressure on your penis.
It is often suggested that various
habits developed in masturbation may make it more difficult to "come" either from other styles of masturbation or indeed, intercourse.
I'd like to know a few more details - whether your girlfriend is in fact able to have you come by way of a "hand job" - the "standard" mode of masturbation? Also, what do you do to pleasure her (with a view to having her "come") - what
can you do effectively? Has
she been able to come during intercourse?
I think your girlfriend is key in this respect - you are going to need a bit of somewhat more specific help from her. Are you presently living with her? If you have manipulative difficulty with the stretching procedures we describe here, it seems to me that you will actually need
her to do it with you. To what extent have you discussed all this with her? No point whatever keeping secrets or matters unsaid. Have you directed her to this site?
A few concepts for you to consider: What you describe about your tight foreskin (let's ignore terms such as "phimosis") is indeed absolutely
normal. And of
course your glans is sensitive - it's
supposed to be and you want it to be so that you
can "come" with reasonable ease. As I frequently, point out, it's much the same as your girlfriend's clitoris which is normally hidden and very sensitive - what can you observe about that?
In fact, your glans (penis head) is not really supposed (nor is your girlfriend's) to be touched/ stroked dry, but only when lubricated. And I'll tell you the secret about oral sex (what I
presume you mean by a "blow job") - saliva
isn't a good lubricant and the mouth
isn't well designed to stimulate a penis - it has teeth for one thing, and although that may be the most sensitive part, the tongue is
only effective in stimulating the underneath of the penis (unless of course, you do it "69"-style).
In addition, your head is rather
heavy and so is your girlfriend's. The women in many societies carry heavy jugs on their heads, but very few are well practiced in moving their head rapidly back and forward for more than a few seconds - it just doesn't work for oral sex. So, if you are acquainted with pornography (which is by
no means a reliable reference point for sexual facts but ...) you may have noted that in order for the fellow to ejaculate, it is necessary for the penis to be stroked - in effect a "hand job" - to stimulate the corona (and frænulum)
as well as whatever the woman is doing with her mouth. Any "thrusting" with her head is brief and largely for theatrical effect!
Clearly, when you
have stretched your foreskin so it is no longer tight (and likely, your frænulum as well) you will have comfortable foreskin mobility and it will do "as it pleases" or offer you more options. In the meantime, at the very minimum you need to have your girlfriend practiced at not only retracting your foreskin, but pulling it forward again so that you do not
need any trips to the doctor to do it for you!
