Remembering Allah During Intercourse to Cure Premature Ejaculation
Question

                I suffer from the problem of premature ejaculation. Can I remember Allah when having intercourse, so that I will remember Allah a great deal and at the same time slow myself down?
Praise be to Allah.
    A number of scholars have stated that it is makrooh 
    (disliked) to mention Allah verbally when having intercourse. 

    An-Nawawi (may Allah have mercy on him) said: it should be 
    noted that dhikr (remembering Allah) is encouraged in all situations, except 
    in situations referred to in sharee‘ah (Islamic law), some of which we will 
    mention here. For example: it is makrooh to remember Allah (verbally) when 
    sitting to relieve oneself, when having intercourse, during the khutbah 
    (Friday sermon) for the one who can hear the voice of the khateeb (orator), 
    when standing during the prayer, at which time one should be focusing on the 
    recitation, and when one is drowsy. End quote from al-Adhkar. 

    Ibn ‘Allan said in his Sharh (commentary): what is meant by 
    dhikr here is remembering Allah verbally, because this is what one is 
    required to refrain from in the cases listed. As for remembering Him in 
    one’s heart, that is required even in these cases. Our companions said: if 
    the one who is relieving himself or engaged in intercourse sneezes, he 
    should praise Allah in his heart. In al-Haraz ath-Thameen it says that dhikr 
    in one’s heart at the time of relieving oneself or engaging in intercourse 
    is not makrooh, according to scholarly consensus. As for remembering Allah 
    verbally at those times, that is not something that is prescribed for us and 
    the Prophet (blessings and peace of Allah be upon him) did not recommend it 
    to us and it was not narrated from any of the sahabah (companions). Rather 
    at such times it is sufficient to be modest and remember that Allah is 
    always watching, and remember the blessing that Allah, may He be exalted, 
    has bestowed by making it easy to expel this harmful matter that, if it was 
    not expelled, might kill one. This is one of the greatest forms of dhikr 
    even if it is not spoken verbally.

    End quote from al-Futoohat ar-Rabbaniyyah. 

    From this you may know that you can remember Allah in your 
    heart, but it is makrooh to utter the dhikr out loud. 

    See: al-Mawsoo‘ah al-Fiqhiyyah.
