I heard that on S.Prabhupada's lectures wich i don't have anymore.
Someone can help?
Also i heard it from Guru Maharaj.
Maybe this quotes:68 11 08 My Dear Hayagriva,and (SB 2 7 6p)can help:
....
I also understand that you do not want to get married now, but if you marry
at all, you should marry now. Because after the age of 30, marriage is not
so pleasing. Practically I am giving in charge of the different centers to
the Grhasthas. If you decide to marry, there are many devotee girls, and one
of them may be a very nice companion for your devotional life. You prefer to
be free, but a devoted wife is as good as freedom. The Grhastha disciples,
just like Syamasundara., Mukunda, and Gurudasa, with their wives, are doing
very nicely in London. Similarly Dayananda and his wife Nandarani are doing
very nicely here.
....The Deity worship must be continued by everyone. Another secret of
success is that when one is very much sexually disturbed he should think of
Lord Krishna's pastimes with the Gopis, and he will forget his sex urge. To
think of Krishna's pastimes with Gopis, but not to try to imitate.
Hoping you are all well,
Your ever well-wisher,

The brahmacäri, or a boy from the age of five years, especially from the
higher castes, namely from the scholarly parents (the brähmaëas), the
administrative parents (the kñatriyas), or the mercantile or productive
parents (the vaiçyas), is trained until twenty-five years of age under the
care of a bona fide guru or teacher, and under strict observance of
discipline he comes to understand the values of life along with taking
specific training for a livelihood. The brahmacäré is then allowed to go
home and enter householder life and get married to a suitable woman. But
there are many brahmacärés who do not go home to become householders but
continue the life of naiñöhika-brahmacärés, without any connection with
women. They accept the order of sannyäsa, or the renounced order of life,
knowing well that combination with women is an unnecessary burden that
checks self-realization. Since sex desire is very strong at a certain stage
of life, the guru may allow the brahmacäré to marry; this license is given
to a brahmacäré who is unable to continue the way of naiñöhika-brahmacarya,
and such discriminations are possible for the bona fide guru. A program of
so-called family planning is needed. The householder who associates with
woman under scriptural restrictions, after a thorough training of
brahmacarya, cannot be a householder like cats and dogs. Such a householder,
after fifty years of age, would retire from the association of woman as a
vänaprastha to be trained to live alone without the association of woman.
When the practice is complete, the same retired householder becomes a
sannyäsé, strictly separate from woman, even from his married wife. Studying
the whole scheme of disassociation from women, it appears that a woman is a
stumbling block for self-realization, and the Lord appeared as Näräyaëa to
teach the principle of womanly disassociation with a vow in life. The
demigods, being envious of the austere life of the rigid brahmacärés, would
try to cause them to break their vows by dispatching soldiers of Cupid. But
in the case of the Lord, it became an unsuccessful attempt when the
celestial beauties saw that the Lord can produce innumerable such beauties
by His mystic internal potency and that there was consequently no need to be
attracted by others externally. There is a common proverb that a
confectioner is never attracted by sweetmeats. The confectioner, who is
always manufacturing sweetmeats, has very little desire to eat them;
similarly, the Lord, by His pleasure potential powers, can produce
innumerable spiritual beauties and not be the least attracted by the false
beauties of material creation. One who does not know alleges foolishly that
Lord Kåñëa enjoyed women in His räsa-lélä in Våndävana, or with His sixteen
thousand married wives at Dvärakä.
