Table 2. Recurring themes and exemplary quotes organized under the model of information, motivation and behavioral skills.

Theoretical component	Primary code	Secondary code	Exemplary quote
Information	Knowledge about condoms	Pregnancy prevention	The first time I heard about condoms was in school, and they related it to pregnancy prevention. At first my parents told me to use a condom so I wouldn’t get someone pregnant.
		STI prevention	When I started talking about HIV, I learned that it was a way to prevent HIV. I know that condoms protect against many diseases.
	Lack of knowledge	Lack of information	When I was young I didn’t know about condoms, I didn’t protect myself for a long time because I didn’t think it was necessary. When I began to have experience in sexual relations I learned about it. I had the habit of using double condoms and not using condoms. They have the idea that there is a risk in penetration but there is no risk in oral sex, so they protect themselves for penetration, but they do not protect themselves for oral sex.
Motivation	Personal motivational experiences	Self-care	One has to take care of the self, and value themselves as a human being, as a person. Over time I realized that I have to take care of my body, so I protect myself when I have sex. I always use it because I think it is a total danger not to use it, how scary to get a disease and damage your life, imagine the Aids, that you have to live with that, with constant treatments, how scary.
	Social motivational experiences	Acceptance by the blood and social family	When a trans girl counts on the support of her family, it greatly influences one’s desire to take care of one’s own health and that of others. In the community-based organization I go to (Santamaría Fundación) they motivate me to take care of my health, to use condoms and to make my partner respect me in my sexual practices. I am very careful in my sexual practices because I am afraid that my family will see me sick, and I will have to deal with an illness.
Behavior	Use	Mistrust of the sexual partner	I go with the client and at once I take out my condom and I uncover it and if the man has a problem because of the condom, I tell him that I am sorry but there is no service. If a man tells me that he pays me more for being without a condom, I already know that this is something dangerous and I refuse to have sex with him.
		Acquisition	I use it when I they are available. I can claim them at health centers and also at foundations. There are many organizations or foundations that give them away.
	Non-use	Characteristics of condoms	Condoms are too tight. Sometimes condoms cause allergies.
		Client’s conditions in sex work	There are trans women who are in need and it’s their turn, so they agree to sex without a condom when they are offered extra money. Nobody shoots porn with a condom anymore. One tries to put the condom on the toy, but if it appears a little bit the client makes them take it off.
		Relations with the sexual partner	The only thing that would influence the use of condoms is if the person is my steady partner for a long time, then it could be eliminated, but otherwise no. Men always say that they don’t feel with a condom. They get angry when you ask for it, and say it’s because they lose sensation. Besides, if you ask for it, they start distrusting you, saying that you are unfaithful.
Behavior	Non-use	Acquisition	There are very expensive condoms; people with limited economic resources cannot buy them because they have other needs. I was ashamed to go to a pharmacy to buy condoms.
		Disinhibition: attraction	When you like a man, the last thing you think about is using a condom. If you like the person, you can do anything in bed, even without a condom.
		Disinhibition: arousal	At the moment of arousal when you forget to use a condom, it doesn’t matter, you don’t even realize it.
		Disinhibition: consumption of psychoactive substances and alcohol	When I’m drunk I lose my mind, become irresponsible; everyone is irresponsible after being drunk. Alcohol makes us do many things, with a glass of alcohol you don’t care if it’s with or without a condom.
		Oral sex	Oral sex with a condom is horrible. I’m more flexible when it comes to oral sex. I do it without a condom.

STI: sexually transmitted infections; HIV: human immunodeficiency virus.
