Question: Dislocated Hips
Yes, you can certainly have sex. Before anything else, talk about your anxiety with your boyfriend. When the two of you are comfortable and talking, and he learns a little about your range of motion and limitations, the two of you will find plenty of things to enjoy together. Remember that if you do something that hurts, it doesn't mean that sex is over. Look at each other, re-connect after the surprise pain, and resume in some other position. If you're female, don't forget to use contraception if you don't want to become pregnant.
