So I have a setting where the main sapient species is a very closely Humanoid race. In this setting, Humans, along with many other species across a number of dimensions, are all descended from an original god-like race called the Originals, who very little is known about. In form, these species all basically resemble Humans, both "Feminoid" (resembling women) and "Masculinoid" (resembling men).
The specific species in this setting are called Stratawan, and they reproduce through use of a large-tree like structure called an Abrogaan. This is a large organism made of bone, which grows "pods" similar to a fruit, and a newborn Stratawan emerges from this pod and then undergoes relatively analogous human development.
Stratawan cannot become Abrogaans, and all Abrogaans are grown from a cutting of another Abrogaan. This makes all Stratawan inherently incapable of individual reproduction, and fairly analogous to worker drones in eusocial species like bees.
This also makes all Stratawan the same sex, because different sexes are largely useless when only able to reproduce through another organism (or, arguably, the Abrogaans are their equivalent of females). In this instance, they fall on the Masculinoid spectrum of species derived from the Originals. This also means that Stratawan would presumably be completely without any form of genitalia.
This means they have no form of parents, and children are either raised communally, or an adult Stratawan will pick a specific newborn and raise it as their child or "Sciall". This is generally reserved for the Aristocracy, as this society is fairly strictly organised into a caste system. This means all "families" are essentially just a series of adoptions.
However, one of my primary intentions with this setting was imagining humanity if it was only composed of Gay Men. As one myself, I wanted the challenge of imagining a society of human-like creatures that was only Homosexual Masculinoids. The Abrogaans are the mechanism by which this species reproduces, as gay males are not capable of child-bearing.
However, this leaves me with a problem. A species that reproduces through the use of another organism is incapable of sexuality, which is fairly core to the culture of gay males. This, in terms of sexuality, more makes them a race of asexuals than anything, which is interesting on its own but was not the authorial intent of this species.
Additionally, there's an argument this race wouldn't even have a form of romantic love. Their reproductive method does not enforce that they must couple in pairs, and while parental and familial (or more accurately tribal) love would definitely exist, romantic love doesn't really necessarily have a reason to exist without sexuality. This isn't how I see it, being a gay male myself and valuing romance without reproduction, but biologically speaking I don't know if this is justifiable.
Given the story planned to take place in this world revolves around a romantic relationship between a member of the aristocracy and a member of the peasantry, love is pretty core to the setting. So the question is whether any form of sexual pleasure could exist in this species, creating a cause for romantic ideals to be developed. Because at the moment I don't know if it's justifiable.
Given that most of this race is naturally raised communally, the question of childcare isn't really an answer to the question either, even though personal child-rearing is a function of this society. Currently there does exist a form of marriage, but it specifically is not intended for child-rearing and more just acts as a legal right for couples to share belongings.
tl;dr I have a humanoid (and masculinoid) species that reproduces through the use of another organism called an abrogaan that grows them like a tree. Would this species have any form of romance or sexual pleasure given this reproduction method?
