Well, hah, thank you for putting in the 'active effort' to answer my battery of questions. =P
So if I'm reading this right, it would probably be fair to say that you mainly just... have a very high sex drive, very much enjoy sex both for yourself and your partner, and any social benefits or detriments that result from that are generally secondary, and you tend toward thinking about the potential or actual consequences of any particular sexual encounter... after they take place.
Entirely not meaning to be rude, but... have you considered that you may legitimately be a nymphomaniac?
Do you... have, generally, persistent thoughts about masturbating or you're just very often quite horny, or you often have thoughts about potentially having sex with almost any one you see, to the point that it breaks your ability to focus or concentrate on other tasks?
I ask because I once met a woman who... described herself as a nymphomaniac, and described it as legitimately debilitating in that she could not focus on studies or being in a classroom... she was quite intelligent, very academically gifted, but described this to me as a very serious daily struggle for her.
Also, some months back, on my old account, I tried to run some numbers on this general topic.
https://lemmy.dbzer0.com/post/35653687/16009784
...if you go by median instead of mean, its probably actually lower than 5 (probably 3 ish?), as 45% of people have had one sexual partner or less.
(That is to say, the 'typical' person has probably had about 3 or 4 sex partners over their whole life, the mean or average of about 5 gets skewed away from that by the 'long tail' of small numbers of people who've had a high number of sex partners)
Displayed in another way:
0 partners : 10% of pop.
1 partner: 35% of pop.
2 - 10 partners: 43% of pop.
11 - 25 partners: 7% of pop.
26 - 40 partners: 4% of pop.
41 - 75 partners: 2% of pop.
76 - 100 partners: 3% of pop.
100+ partners: 3% of pop.
Not trying to slut shame at all, but... you having 100+ partners by age 24 is... highly uncommon, an outlier, as you say, so I very much value the ability to ask such a rare outlier for their perspective and experiences.
IIRC, those numbers are for total lifetime sex partners of people of all ages, and you are already nearly outside of 2 standard deviations by age 24, you'd be likely to get outside of 3 std devs if you keep up this pace for another decade.
(1 std dev each way from the mean captures 68% of a data set, 2 std devs captures 95%, 3 std devs captures 99.6%)
((also, iirc, these numbers are for USAmericans, they could potentially and probably do differ somewhat by geographic location, different cultural norms, etc))
(((also also, these numbers are just for people generally, not specific to any sex or gender or sexual orientation)))
Segueing from that; yes, of course, myself and the nymphomaniac ended up being FWB for a while, where I can give you this uh, specific data point:
We once set aside a literal entire day for sex, and we fucked for at least 8 hours straight. Literally sun up to sun down.
We had planned to try to keep track of, but eventually both lost count of how many times we came, and literally had to take the entire following day off to physically recover, as if we'd just done an all day bar crawl and were horrendously hungover.
So, hah, you had any sessions go over 8 hours?
