If he has intercourse but does not ejaculate, ghusl is still required

 

If intercourse takes place but climax (emission of semen) is not reached, do they both have to take a bath? If they do not feel any desire, can they resort to the secret habit?.

Praise be to Allaah.

Firstly: 

If
intercourse takes place, i.e., if the tip of the penis disappears in the
vagina, then ghusl is obligatory for the man and the woman, even if no semen
is emitted, because of the report narrated by al-Bukhaari (291) and Muslim
(348) from Abu Hurayrah (may Allaah be pleased with him) from the Prophet
(peace and blessings of Allaah be upon him) , who said: “When a man
sits between the four parts (arms and legs of his wife) and has intercourse
with her, then ghusl is obligatory.” 

Muslim
added: “Even if he does not ejaculate.” 

Ibn Qudaamah
(may Allaah have mercy on him) said in al-Mughni (1/131): The fuqaha’
are agreed that ghusl is required in this case, except that it was narrated
that Dawood said it is not required. End quote. 

Secondly: 

It is
permissible for a man to enjoy his wife and for a woman to enjoy her
husband, however they want, so long as they avoid intercourse at the time of
menstruation and anal intercourse.  That includes each of them masturbating
the other. This comes under the heading of enjoyment that is permitted
according to the verse (interpretation of the meaning):  

“And
those who guard their chastity (i.e. private parts, from illegal sexual
acts)

6. Except
from their wives or (the slaves) that their right hands possess, ___ for
then, they are free from blame”

[al-Mu’minoon 23:5-6] 

But if a man
masturbates by himself or a woman masturbates by herself, this is haraam.
That has been explained in the answer to question no.
329. 

And Allaah
knows best.
