Oral sex, Anal sex

Is oral sex & anal sex permissible for Christians.
A devout sister said that oral sex and watching porn is permissible as long as you practice it with your partner in marriage. If it is wrong to practice it, have the marriage become a license to sin?
What about anal sex? Is doing it with a woman as good as doing it with a man?

Far as watching porn in marriage, i'd say that's a no. Porn is about lust and selfishness and nothing else. Women in particular, but men as well, are told to be modest in appearance for a reason. To discourage getting the wrong attention or provoking wrong thoughts. So if Christian women are to dress modestly so as to not risk arousing desire, and men are to not focus their eyes or thoughts on womens bodies, then how can watching naked people have sex be right? And if you need outside stimulation within your marriage to maintain a healthy sex life then that indicates a bigger problem. 'Devout' doesn't equate to being right.
Far as anal and oral sex, that's going to be up for debate. Some people say these are acts only for homosexuals because they can't have regular sex. So performing them, even on your spouse, to them, is the same as performing a homosexual act. Other people see it as a natural part of sex.
But is anal sex with a woman 'as good' as with a man? Umm.. i've never thought of any sex of any kind with a man as 'good' so i have no answer for that.

1 Corinthians 10:23 KJV
[23] All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not.

All things are legitimate [permissible–and we are free to do anything we please], but not all things are helpful (expedient, profitable, and wholesome). All things are legitimate, but not all things are constructive [to character] and edifying [to spiritual life]. (*1 Corinthians‬ *10‬:*23‬ AMP) I Love you Brother

"Let her be as the loving hind and pleasant roe; let her breast satisfy thee at all times; and be thou ravished always with her love" (Prov.5:19)

"Let her breast satisfy thee"
Like a baby is satisfied by its mothers breasts

"be thou Ravished always..."
Heb. shagah [shaw-gaw'] meaning:- to go astray, to err, be intoxicated

"And why wilt thou, my son, be ravished [go astray, to err, be intoxicated] with [pleasurable desires] with a strange woman?" (v.20)

If thou wilt be go astray, err, (v.20) then be thou intoxicated with pleasurable desires of which thy love for thy wife worketh in thy bed; yet keep it undefiled and be not conformed to the standards of this world. He who go into a strange woman " in the greatness of his folly he shall go astray [be ravished]" (v.23)

WHERE DO WE DRAW THE LINE?
"For the ways of man are before the eyes of the Lord" (Prov.5:21)
Why does men seek the company of strange women?
Isn't it for intoxicating sexual pleasures, and now Solomon says, if so, let it be then with thy wife.
In whatever you practice, know this that your ways are before the eyes of the Lord.

Hmm!

Respectfully i´d say I have nothing to do with a man... and, as far as I seen and done, ladies like it (not all).

I never had seen one woman having orgasms with anal sex but now I know and understand why some sodomite could be enjoying that: Some ladies might like it and, after what I have seen, I understand way sodomites could like it.

By the way! That woman was in the time where she was starting to menstruate and I had better being profilactically "isolated", like the Bible said.

Read these to see what´s best.
