how to tell him im ready

my boyfriend has respected the fact that im not ready to have sex due to a traumatic experience i went through back in march. He told me to take as much time as i need😫❤️

I think im ready to have sex or maybe just oral. However, I don’t know how i wanna tell him. When we were together, I asked him how he would react if i told him i was ready and he said he’d think i was joking and start laughing. Idk maybe im not ready and im just super horny😂🤷🏽‍♀️
