Intimacy

Tips

Though certain sexual acts may be traditionally associated with a binary gender, or with femininity/masculinity, this is not inherent.
Communication before, during, and after sex is vital. For example:
- Make it clear what acts you are comfortable with, and which ones you do not want to do. Consider working on a "Yes/No/Maybe" list for yourself and your partner(s).
- Let your partner(s) know if there are certain words (for anatomical parts, terms of endearment, etc) that you want them to use or avoid.
- Let your partner(s) know if there is an area of your body you do not want touched, due to dysphoria or any other reason.
- Let your partner(s) know if you need to stop, take a pause, or change activities during the encounter for any reason.
Orgasming is good, but not required for sex to be satisfying. Depending on hormonal levels, dysphoria, or other reasons, orgasm may be very difficult or impossible for someone to achieve.
Penetration is also not required for sex (and may be difficult or impossible for the same reasons as listed in previous point).
Consider if you need to use safer sex tools (internal condom, external condom, dental dam, etc) for birth control and/or preventing infection transmission. Keep in mind that hormone therapy does not fully prevent fertility.
