2/ Regarding oral sex
Response: I will respond to the likes of this question by saying:
This is from the actions of some of the animals such as the dogs.
We have a general principle, and that is the Messenger (sal-Allaahu 'alayhe wa sallam) forbade (us from) resembling the animals in other than what we are talking about (oral sex); Such as his forbidding the placing of the knees on the ground before the hands (when going into sujood) just as the camel[1] does; And looking around (in the salaah) like a fox[2]; And pecking (in the rukoo' and the sujood) like a crow[3].
And since it is also known that the Prophet (sal-Allaahu 'alayhe wa sallam) forbade (us from) resembling the disbelievers, then it is understood from this to be a prohibition; Also affirming the prohibition in what has preceded regarding the resembling of animals, especially since that which is known about them is their filthy nature; So, with regard to this action (oral sex), the Muslim must be far above and removed from resembling the animals.

Certain cases of mouth cancer appear to be caused by a virus that can be contracted during oral sex, media reported, quoting a new Swedish study.
People who contract a high-risk variety of the human papilloma virus, HPV, during oral sex are more likely to fall ill with mouth cancer, according to a study conducted at the Malmo University Faculty of Odontology in southern Sweden.
"You should avoid having oral sex," dentist and researcher Kerstin Rosenquist, who headed the study, told Swedish news agency TT.
HPV is a wart virus that causes many cervical cancers, including endometrial cancer (in the uterus).
Comparing 132 patients with mouth cancer with a control group of 320 healthy people, Rosenquist found that 36 percent of the cancer patients were carriers of HPV while only one percent of the control group had the virus.
The main factors that contribute to mouth cancer, most commonly contracted by middle aged and older men, are smoking and drinking alcohol, scientists agree.
"But in recent years the illness has been on the rise among young individuals and we don't know why. But one could speculate that this virus (HPV) is one of the factors," Rosenquist said.
Her findings confirm other international studies in recent years.
3/ The Ruling Regarding Masturbation
Onanism is masturbation with the hand - which is prohibited; It is obligatory upon all Muslims to take precaution against it, because doing it is contrary to the statement of Allaah ('Azza wa Jall):
{And those who guard their chastity (i.e. private parts, from illegal sexual acts). Except from their wives or (the slaves) that their right hands possess, – for then, they are free from blame; But whoever seeks beyond that, then those are the transgressors}, [Soorah al-Mu.minoon, Aayahs 5-7]
In addition to that which exists in masturbation of much [health-related] harm.
And Allaah is the Expounder of All Success.

4/ Expiation for haraam sexual activity
According to a report narrated by ‘Abd-Allaah, a man came to the Prophet (peace and blessings of Allaah be upon him) and said, “O Messenger of Allaah, I fondled a woman in the furthest outskirts of Madeenah but I did not actually have intercourse with her. Here I am, judge me as you wish.” ‘Umar said to him: “Allaah had covered you, you should have covered yourself (i.e., you should not have spoken of it).” The Prophet (peace and blessings of Allaah be upon him) did not reply at all, so the man got up and left. The Prophet (peace and blessings of Allaah be upon him) sent a man to follow him, call him and recite to him the aayah (interpretation of the meaning): “And perform al-salaah at the two ends of the day and in some hours of the night. Verily, the good deeds remove the evil deeds (i.e., small sins). That is a reminder (advice) for the mindful (those who accept advice).” [Hood 11:114]. A man who was present said: “O Prophet of Allaah, is this just for him?” He said, “No, it is for all the people.” (Reported by Muslim, 4964).
