Well, as a woman, let me answer this from MY perspective!
Why do you think a lot of women prefer their lovers cum inside their pussies?
I don't think a lot of women prefer their lovers cum inside their pussies - I think most, if not all women prefer it! After all, it's natural. It's where it's supposed to go. And there is a basic urge for the woman to want it there. I also think that oral sex, to completion, is both a product of the porn industry and a waste. The porn industry is catering to the male fantasy of the female being submissive, taking his cock into her mouth and letting him ejaculate - all his pleasure with a lot less for her. We all know that once a guy cums, he's done, for at least a little while. She might have gotten some satisfaction from making him cum, but I don't know many women who obtain an orgasm from sucking a guy off.
When a guy cums inside a woman, it's the culmination of what she was designed to do; receive his DNA. Even if she is on Birth Control, that basic urge is always present. When he does, she (speaking for myself) receives a very high degree of satisfaction - that she pleasured him enough with her body to make him inseminate her! Personally speaking, I almost regard it as a gift and am reluctant to clean out afterwords.
Why do you think a lot of black males enjoy cumming inside pussies?
ALL men enjoy cumming inside of pussies, not just Black men! To a degree, he's 'claiming' her. She found him attractive enough to allow his cock inside of her body, unprotected. When he mounts her, he has but one basic objective, to inseminate her; to fill her with his seed, his DNA, in the instinctual goal of impregnating her. If he is considerate and skilled, he will also ensure her orgasm, but sadly, that isn't always the case. When he does ejaculate inside the woman, he has obtained his basic goal.
With Blacks, I think it's amplified. Not only are they mounting a woman, but a WHITE woman finds him attractive enough to allow him to have her! That must be quite the ego stroke for him! Compounding that, if she is married, there is the realization that he is 'claiming' her over her husband. There must be some motivation for her to seek out a Black male, and he, this particular Black male, is the one she sought out. Again, a huge ego boost!
Why do you think a lot of husbands wish to see their wives' pussies filled with black sperm?
I know my husband does. He has said that it is as though I'm still sexy enough to attract other men, yet I still go home with him. The fact that it's a Black man compounds that. He is having me, yet giving me a tremendous amount of pleasure in the process. Seeing me being inseminated by a Black is as much a turn on for him as it is for me! From my experience, after my Bull has had me, my husband and I have sex like teenagers for at least a week afterwards, something that I enjoy tremendously! So it's a win-win-win. Everyone gets what they want: My Bull gets to have me, a White married woman; I get to enjoy the raw uninhibited sex a Black man delivers, and I'm driving my husband into an intense sexual arousal in the process; and finally, my husband gets to satisfy his fantasies - resulting in outstanding sex with me for an extended period of time.
That's my perspective at least. I'm sure other women in the forum have vastly different opinions and attitudes towards your questions. And you know, they are 100 percent right - whatever works for them is perfect in every possible way, or they wouldn't do it!
Again, my perspectives. Always welcome other views!
