Sexuality

Sexuality and sex are topics touched upon frequently within MS Paint Adventures, especially the topic of gender and forms of romance which are prevalent in Homestuck and its spinoffs.

In Homestuck
Homestuck features various forms of romance which tend to differ between species.

Human romance
There is only one form of generalised human romance, known as "love" and represented by the heart symbol. Although "HS 6007 " human sexuality is varied, and Homestuck depicts various non-heterosexual relationships. Dirk Strider is attracted only to other men, but considers the term "gay," commonly used to refer to non-heterosexual relationships between men, to be "HS 4488," possibly due to his version of Earth 's exposure to Alternian reproductive norms.

Troll romance
As opposed to those of humans, troll reproductive pairs are HS 6007. It appears to be because of this that terms like "homosexual" are not "HS 2628 (") in the Alternian vocabulary.

Cherub romance
Like human romance, cherub romance features only one type, equivalent to the "hate" represented by the spade symbol in troll romance. Also like humans, their reproductive pairs could be described as "heterosexual," but in addition to two binary sexes each cherub is also born with one of two "HS 5963" which must oppose that of their potential mate.

Carapacian romance
Though little is known about the exact nature of carapacian romance, they appear to form heterosexual pairs similar to those of "love" found in human culture, such as that between the White King and Queen. In addition to this, however, carapacians have been known to form pairs that are "HS 2395," such as that between Jack Noir and the Black Queen, whose relationship has occasionally HS 3856 (represented by the spade symbol found in troll romance).

Leprechaun romance
Of the described forms of romance in Homestuck, Leprechaun romance is the least well-understood. As opposed to human romance, which requires only one symbol to be described, and troll romance, which requires four, leprechaun romance requires nine symbols, each representing a form of romance HS 6007 (and) than those of either of the other two races. According to Aranea, one of the symbols (presumably the pink heart) represents romantic "love" as understood similarly by both humans and trolls, but none of the other symbols are comparable, with no equivalents to black and red or conciliatory and concupiscient romance.

Other forms of romance
In addition to extensive knowledge on the topics of romance among trolls and leprechauns, Aranea also HS 6032 (claims to be knowledgable) in the topics of and, but does not elaborate on her knowledge.

In Problem Sleuth
Gender is represented in simplistic binary terms in Problem Sleuth, with most male characters having alter egos of the opposite sex, save for those who lack the imagination to think of one. Andrew Hussie describes this as PS 625

In Homestuck
For much of Homestuck, gender is used in a similar simplistic manner to in Problem Sleuth. Every known Sburb session has included an even number of male and female players (save for Caliborn and the alternate Calliope 's one-player Dead Sessionsn after they killed their other players), as do both ectobiological families among the human players. Trolls share genders with their ancestors, and seem to refer to their lusii in kind, though Jasprosesprite^2 believes that animals like cats HS 7895

Davepetasprite^2 is the first character in Homestuck to actively question their gender, feeling unsure of what matters to them due to their constituent parts, Dave Strider and Nepeta Leijon, both having deep feelings regarding their identities as a boy and a girl, respectively.

Despite their bisexual nature, trolls appear to still have established roles for each gender, with Karkat describing Flarp as being "HS 2177." In A6I3 , Porrim describes Alternia as being subject to a due to the influence of Lord English and his control over Her Imperious Condescension. This gender heirarchy on Alternia is likely interconnected with the heirarchy of the Hemospectrum, with "CIPs" (cobalt-, indigo- and purplebloods) being described as "", leading to a and  on Beforus.

In the Homestuck Epilogues
Gender plays a bigger role in the Homestuck Epilogues than in their predecessor, with Roxy and Calliope describing their experiences with it and experimenting with their identities in both the Meat and Candy epilogues.

Roxy describes gender as "", with Calliope stating that their notions of gender "" Calliope also supports Porrim's assertion that Lord English influenced Alternia's gender roles, stating that their own observations of human gender alongside Caliborn's "" which in turn influenced that of Earth. From this Roxy concludes that "."

Because of this, in the Meat epilogue Roxy goes on to identify as a male and use masculine he/him pronouns. In the Candy epilogue, however, Roxy states that they aren't "" and seems to continue to use the same feminine she/her pronouns as in Homestuck.
