I’ve heard mixed opinions and strange assumptions like, “masculine ppl are attracted to them”, “they’re angry people”.
A key component to recognize about the fire houses (1, 5, 9) is that they have a lot to do with one's identity. The 5th house illustrates an individual's ability to create as well as parts of themselves that they seek (being the precursor to the 9th house' purpose). Sometimes we seek ourselves through others hence why the 5th house is associated with attraction, it shows desire and what we are drawn to. The things we are drawn to play a part in aiding or building our identity. So with this all in mind, your 5th house says less about this sense of "other" where there's a group or type of person attracted to you, but more so what you're attracted to and people that share a relatability with you. There's a harmony at play because of the 5th house' relationship to your ascendant or 1st house.
It would make more sense that you're attracted to martian type people. This could be masculine people, but it can be broader than that– it can be ambitious people, people with a very active lifestyle, maybe someone who's kind of edgy, someone who is willing to take risks, and so on.
In response to “they’re angry people,” Mars in Scorpio is a lot more subdued in their expression thanks to being in a water sign. Mars in the water signs makes for expressive complexity for sure though. Aspects would be more telling of what this looks like as an average functioning person isn't likely to be just an angry person. There's usually a root to anger, or a proneness to being angry that I would search for in the chart before labelling a domicile Mars in the chart an angry person signifier. Aspects to any of the other personal planets with Mars for sure tells a story about someone's relationship with anger.
In general, Mars in Scorpio when faced with conflict can be cunning and eloquent in their solution. In its negative expression– jealous, vengeful, self-sabotaging, and manipulative. Unlike Mars' other home placement in Aries, Scorpio is NOT reckless. Risks are not taken without very careful consideration of the outcome.
Mars represents one's life force as well. So the house its occupying will tell you what you do in order to maintain your life force. Mars being in the 5th house means you need consistent hobbies in order to stay sane and feel good physically. There's likely a strong interest in Martian hobbies (and this is a broad bubble of things... could be cars, sports, fitness, anything that involves building or constructing, martial arts, and so on. With Scorpio being involved, there might be an occult or edgier touch in your hobbies/interests). A strong social life is important too, particularly romantic connections. a watery Mars in the 5th is drawn to substances, particularly alcohol. Despite this feeling great for maintaining one's self, obviously practice caution with this vice.
