Thanks for your help. I greatly appreciate it.
My fiancee is sexually submissive. She will do anything sexually that is not degrading. She told me that she had anal sex with her former boyfriends because they wanted it. Outside of a bedroom, my fiancee is far from submissive.
My fiancee explained anal sex in detail to me. She said anal sex is not as depicted in porn where an actor inserts his dick into an actress's butt.
My fiancee told me her first experience with anal sex was not positive. Neither her then boyfriend nor she knew what they were doing. He managed penetrate her ass with his dick heavily lubricated with Vaseline. It wasn't until college that she learned how to have pleasurable anal sex with silicon lubricant.
According to my fiancee, anal sex began with a guy massaging her ass with his fingers. I almost always massage my fiancee's ass with my fingers. She does enjoy anal stimulation. After a guy had massaged her ass, he'd slowly insert a heavily silicon lubricated finger into her ass. After he was able to slowly thrust his finger in and out of her ass, he'd insert another heavily lubricated finger inside of her ass until her ass was sufficiently dilated. She'd apply a lot of silicone lubricant in her hand and rub it all over a guy's cock.
After a few years of having anal sex with a few or more men, another boyfriend introduced her to anal plugs. She enjoys anal plugs to this day, and I'll insert one into her ass before I lick he clit to massive orgasm.
My fiancee told me that a guy's best penetration of her ass was with her ass over the edge of a bed with her thighs under her chest and her chest on her thighs and her ass slightly elevated. After her ass was sufficiently dilated, he'd slowly attempt penetration from behind her. If he was able to slowly penetrate her ass, she'd tell him she was good. He'd begin thrusting slowly at first before he'd be able to thrust his dick inside of her ass as though her were thrusting inside of her pussy. She said men came very, very quickly while having anal sex with her. She had a boyfriend with a long dick who was able to completely penetrate her ass.
My fiancee told me that anal sex takes a lot of prepping of her ass. She had to assure her anal canal was clear. She said it was best for her if she had been drinking prior. She said silicon lubricant caused anal sex to be very messy. After guys came, she took showers with them so she could scrub their dicks before having vaginal sex with them. She was cognizant of potential bacterial infection caused by fecal matter inside of her pussy. She did not trust guys to scrub their own dicks. She did it.
My fiancee told me that after guys had anal sex with her, it often stimulated her to poop. From memory, at least two of her former boyfriends gave her enemas before they had anal sex with her. In my opinion, defecation and sex don't mesh.
To me, anal sex sounded like too much work. I could have cum by vaginal sex or a blow job by the time one of her former boyfriends got a second finger inside of her ass. Just dilating her ass sufficiently to accept a guy's dick sounded like a lot of work.
Maybe if my fiancee had offered anal sex to me when I was younger, I might have taken her up on her offer. But when I was younger, I was never in to anal sex. I know a lot of men love anal sex. My fiancee told me that her former boyfriends loved having anal sex with her. She told me that if done correctly, it was enjoyable for her; however, she greatly prefers massive orgasms from my tongue on her clit. She has told me she's completely good not having anal sex. She has told me that vaginal sex is much more pleasurable for her than anal sex.
One more point: after my fiancee asked me if I wanted to have anal sex with her, I researched, anal sex. I read about anal sex orgasm. I asked my fiancee if she has ever had an anal sex orgasm. She said it was physiologically impossible to have an anal sex orgasm, There is no human mechanism in anal canals to stimulate orgasm. Anal sex alone was pleasurable for her but not orgasmic. She did have trembling orgasms while a boyfriend was having anal sex with her and she masturbated her clit to orgasm. Her masturbating her clit caused her orgasms, not anal sex.
