There seems logical to think that there's a big gap between a young man and an elderly one, inclusive in terms of sexuality.

Several are the modifications in physical and psychic terms, being such fairly specific of each individual.

Usually conceptualization of sexual alterations of man begins from around 40/50 years of age as sexual dysfunctions of the elderly man, and dysfunctions of erection and sexual desire that stand major importance for the sake of clinical practice.

Roughly, these two dysfunctions are, once discarded any given organic cause, intrinsically related to a couple's daily routine. It's represented by monotony and automatism of relations, as well as stress, overdoing on eating habits, alcohol and tobacco, besides anxiety likely to be experienced by the man when noticing that, in front of erotic stimulus, his penis no longer reacts as promptly as previously, characterizing the fear of sexual performance.

There should be bore in mind that, as we get older, also sexual desire tends to diminish somehow, being this fact accepted as a physiological alteration stemming from the ageing process. However, there should be well established what diminishing desire is and what is lack of interest for sex. Although both share certain common causes, the psychological pattern is quite distinctive between both of them.

Highly varied are the changes in terms of physiology of sexual response in mature man given that the dysfunction in relation to the youth lies in the duration of each phase of sexual cycle.

In mature man or elderly erection is usually slow, much as penetration and ejaculation while loss of penial intumescences after orgasm is fairly quick, taking generally a couple of seconds, in contrast to a young man who features rapid erection, precocious ejaculation and quirk ejaculation with slow loss of intumescence.

It's notorious the physical modifications with respects to a mature man's genitals. The scrotum turns less elastic and the testicles lose growth capacity owing to a lack of vase congestion, apart from having a drastic reduction of the testicular elevation.

The ejaculatory contractions appear in lesser quantity, duration and intensity and noticeably a considerable decrease in the strength of ejaculated release, which generally not surpass over 30'-in youth, spur might range from 30' to reach as far as 60' and over of ejaculatory matter from the urethral sphincter.

Furthermore, the refractive period tends to augment considerably after the 50's, likely to suffer variations of hours and even days until the next erection.

Obviously, all of such reactions oscillate individually and not all individuals display them all at the same time.

Fundamental is to be aware of personal limitations and to respect such alterations stemming from ageing. Taking the most out of self-experience, seeing that vigour of youth cannot be recruited any longer.
