Monkeypox can spread to anyone through close, personal, often skin-to-skin contact, including:
Direct contact with monkeypox rash, scabs, or body fluids from a person with monkeypox.
Touching objects, fabrics (clothing, bedding, or towels), and surfaces that have been used by someone with monkeypox.
Contact with respiratory secretions.
This direct contact can happen during intimate contact, including:
Oral, anal, and vaginal sex or touching the genitals (penis, testicles, labia, and vagina) or anus (butthole) of a person with monkeypox.
Hugging, massage, and kissing.
Prolonged face-to-face contact.
Touching fabrics and objects during sex that were used by a person with monkeypox and that have not been disinfected, such as bedding, towels, fetish gear, and sex toys.
A pregnant person can spread the virus to their fetus through the placenta.
Whether sexual contact is protected or unprotected is moot when considering the above.
People who say that this is a lifestyle risk - so is smoking, being fat and not taking exercise, excessive alcohol intake - there are multiple lifestyle choices that infer a degree of health risk.
