There is nothing in the whole hadees suggesting that anybody was having sex, nothing at all.
Secondly, seeing anyone naked doesn't mean that he is homosexual.A mother who changes diaper, sees her child but it doesn't make her pedophile or homosexual.A gyenecologist sees her patients, but definitely she is not homosexual,a nurse vaccinating is not a pedophile too.It is just the abnormal psychology of the idiot foolish delusional critic, who must go to any mental institute for some rehabilitation.
The hadees mentioned by the critic is:
Anas (may Allaah be pleased with him) who said: “The Prophet (peace and blessings of Allaah be upon him) used to relieve himself, then another boy and I would bring a vessel of water and a short spear [to use as a sutrah for the prayer he was going to do after doing wudoo’] and he would cleanse himself with the water.”
Note the word Then and the word wudoo
See the ahadees in the following
It was narrated that Al-Mughirah bin Shu'bah said:
"The Prophet (ﷺ) went out to relieve himself, and when he came back, I met him with a vessel (of water). I poured some for him and he washed his hands, then he washed his face. Then he wanted to wash his forearms but his Jubbah was too tight, so he brought them out from beneath the Jubbah to wash them, and he wiped over his Khuffs, then he led us in prayer."Nasai 125
Al-Mughirah b. Shu’bah reported:
I was in the company of the Messenger of Allah (ﷺ) in the expedition of Tabuk. He abandoned the main road before the dawn prayer, and I also did the same along with him. The Prophet (ﷺ) made his camel kneel down and (went to ) relieve himself. He then came back and I poured water upon his hands from the skin-vessel. He then washed his hands and face. He tried to get his forearms out (of the gown), but the sleeves of the gown were too narrow, so he entered back both his hands, and brought them out from beneath the gown. He washed his forearms up to the elbows and wiped his head and wiped over his socks.80 He then mounted (his camel) and we began to proceed until we found people offering the prayer. They brought forward ‘Abd al-Rahman b. ‘Awf who was leading them in prayer. The Prophet(ﷺ) stood in the row side by side with other Muslims. He performed the second rak’ah of the prayer behind ‘Abd al-Rahman b. ‘Awf. Then ‘Abd al-Rahman uttered salutation. The Prophet(ﷺ) stood to perform the remaining rak’ah of the prayer. The Muslims were alarmed. They began to utter tasbih (Subhan Allah) presuming that they had offered prayer before the Prophet (ﷺ) had done. When he uttered the salutation (i.e. finished his prayer), he said: You were right, or (he said) you did well.Sunan Abu Dawud 149
The words wudoo in the hadees mentioned by the critic himself and the terms highlighted in the above mentioned ahadees are clear to conclude that they were carrying vessel just for wudoo, to pour water upon the hands of Prophet Muhammad s.a.w.w so that he would wash his hands and face and forearms.
