here! quick little drawing of Tron/Ram.
ALT…..so, sometimes a shepherd will paint the chests of their rams in colored chalk so that they can know, by the colors of the ewes’ backs, which have been the mates of which.
circuits sometimes do a similar thing.
(and yes. This means sometimes Tron is the one getting mounted from behind. Ram’s main preference, after all, is that he gets great feelings from helping folks with their needs… whatever those may be.)
(and I find it hard to deny that Tron’s needs would sometimes include getting… rammed.)
