While many men begin a slow but gradual decline in their 30s, there is no reason,
assuming good health, that a man should not be able to perform sexually well
into his 70s and beyond. Although a new study revealed that about half of all
men over 40 have occasional problems with erections, this is often caused by
other factors (whether emotional or physical).
On the other hand, as men age, there are changes that do take place. You will
probably notice a difference between your new boyfriend and any previous
partners you have had who were closer to your age. First, as men get older,
they tend to take longer to get an erection and require more stimulation.
Whereas men in their teens and early 20s often can't control how many erections
they get, men in their 40s often need direct stimulation to become erect.
Another difference is that as men age, they require a longer recovery period
between orgasms. While a man in his early 20s can often become erect after just
a few minutes, men in their 40s often require several hours between ejaculations.
However, there are also many positives. For one, men your boyfriend's age are
less likely to have problems with premature ejaculation and will have more
control. Plus, there is some truth that experience counts for a lot when it
comes to sex. Men in their 40s are often far more attentive to their partner's
needs and how to fulfill them.
So, yes -- there might be some differences, but sex is likely to be as good or
even better with older men than with younger ones.
