Messenger of Allah ﷺ forbade ʿUthman bin Maz'un to abstain from marrying (and other pleasures) and if he had allowed him, we would have gotten ourselves castrated.  

سَمِعْتُ سَعْدَ بْنَ أَبِي وَقَّاصٍ يَقُولُ رَدَّ رَسُولُ اللَّهِ ﷺ عَلَى عُثْمَانَ بْنِ مَظْعُونٍ التَّبَتُّلَ وَلَوْ أَذِنَ لَهُ لاَخْتَصَيْنَا  

Sa'd said: “The Messenger of Allah disapproved of Uthman bin Maz'un's desire to remain celibate; if he had given him permission, we would have gotten ourselves castrated.” (Using translation from Ibn Mājah 1848)   

سَمِعْتُ سَعْدَ بْنَ أَبِي وَقَّاصٍ يَقُولُ لَقَدْ رَدَّ رَسُولُ اللهِ ﷺ عَلَى عُثْمَانَ بْنِ مَظْعُونٍ التَّبَتُّلَ وَلَوْ أَذِنَ لَهُ فِيهِ لاخْتَصَيْنَا  

The Prophet ﷺ prevented ʿUthman bin Mazun from that (not marrying), and had he allowed him, we would have got ourselves castrated. (Using translation from Bukhārī 5074)  

أَنَّهُ سَمِعَ سَعْدَ بْنَ أَبِي وَقَّاصٍ يَقُولُ «لَقَدْ رَدَّ ذَلِكَ رَسُولُ اللَّهِ ﷺ عَلَى عُثْمَانَ وَلَوْ أَجَازَ لَهُ التَّبَتُّلَ لَاخْتَصَيْنَا»
