People are typically happier with more sex, but this BBC thing is a meme from porn. On average, blacks have a penis size about 2% longer than whites (penissizes.org/average-penis-size-ethnicity-race-and-country).
Women are going to nag whether or not they've had a dick in them. If you can't satisfy your partner, you shouldn't be with them.
Women tend to cheat emotionally, with an investment in a new partner they perceive better than their current. This highlights something at the core of female nature: hypergamy. Women can only have one kid at a time, and will typically select the best available mate.
If you let her know it's fine with you to be with someone else, do you really think she won't take that extra step and just find someone better than you? It's a logical fallacy to assume that she'll only cheat with black guys, or that you'll know about it.
Cons:
-STDs
-Children that aren't your own
-Psychological and emotional trauma involved with your partner wanting someone over you
Assumption 1: Scarcity brings value. This is something that can be universally observed; if there's less of a thing it's worth more. From neurotransmitter uptake sites that degrade with oversaturation and increase with undersaturation, to basic economics, this is effectively a law of nature.
Assumption 2: Sex is the most intimate thing that can occur between people. There is obviously potential to have extreme openness between people without sex, but sex forces the issue. During orgasm your brain is bathed in oxytocin and vasopressin which cause attachment. Sex also stimulates production of dopamine which is associated with the reward center of the brain, reinforcing the concept of pleasure to be linked with the person causing it.
3: Black STD rates are significantly higher than other minorities. Going off the information from (cdc.gov/std/stats14/minorities.htm) blacks men, with respect to white men, are:
-730% more likely to have chlamydia
-1060% more likely to have gonorrhea
-530% more likely to have syphilis
-845% more likely to have HIV (cdc.gov/hiv/pdf/library/slidesets/cdc-hiv-surveillance-race-ethnicity.pdf)
Assumption 4: Children not your own. I think this is a fairly obvious one; if more than one man is having sex with a woman and she gets pregnant, either man could've been the father. Condoms break, birth control fails; these are not viable defences against this.
I've had sex with love, and sex without. When there's love it's genuinely one of the best things life has to offer, without the love it might as well be masturbation. I can't support cuckoldry from a logical or emotional standpoint as outlined above. While I do agree that sex can be just sex, I don't believe it should be cheapened when there's so much of a potential for it to be more than that.
