to look on the "net" for possible "causes" of "premature ejaculation".
There really is only one "cause", which is that you are sexually excited, and that you are young
. Let me tell you that it is most
unusual for older men to suffer such a complaint.
I really must impress this on you. Your body is functioning absolutely normally
you place your erect penis in a young lady's vagina (or indeed, something resembling it), it obediently responds by discharging your semen into her. That's exactly
what it is "designed" to do. Such things as spending time doing this, or having her experience an orgasm in the process (which is in fact, relatively unlikely anyway), are nothing more than luxury embellishments on the process.
And it is also the case that one
form of masturbation some men practice as alternative to rhythmic stroking, is indeed just that - to pull the foreskin (or remnant skin in the case of circumcised men, for whom this is necessarily far
less effective) down from the glans maintaining a consistent tension (possibly with some repetitive movement) to result in ejaculation.
You are therefore speaking not of some "abnormality" for which there is a "treatment" (so it becomes pretty meaningless to refer to operations or "cures" on the NHS), but of what manipulations you might employ to slow down this process. Certainly, stretching the frænulum (and possibly the foreskin opening as well) will probably reduce the sexual sensation of holding the foreskin tightly back, and we completely and strongly encourage you to proceed with this.
In the more general sense, I (and backed up by our local experts in sex therapy,) suggest that "diversionary" approaches (thinking about something unpleasant, whatever or whomever that might be) are of little use, nor are using anaesthetic agents - because the actual
nature of the stimulation is not the most important part of the process, rather the feeling
and excitement of being in sexual contact.
Probably the most
effective ploy (other than SSRI medication which to varying degrees, does effectively block the sexual reflexes which result in ejaculation and which might
be available through the NHS), is "two bites at the cherry" - simply allowing
yourself to ejaculate soon, then shifting to some alternate sexual activity (which is to say, attending to your lady-friend's stimulation which is most important in itself) until you re-develop an erection which should then be less susceptible to such dramatic stimulation.
