I’ve been using “selective companionship” for at least 30 years. Some have cum, some have not. I was disappointed but it was my fault not requesting in advance. For that point on, I request it in our negotiations. Sometimes I’m specific - if it’s BB, I request breeding, sometimes it’s swallowing. If we are spending the night, I might ask for both. Sometimes I’m less specific - can you come? Sometimes he’ll ask “do you want me to cum?” You simply have to start the conversation.
