My fiance and I have been together about 2 years. I love the man. We have had our issues. Him on dating sites because he feels I'll leave him and he wanted one foot out the door. We got through it after our son died, but now i am 24 weeks pregnant and all i want is sex. 24-7. Which he doesn't mind but all im craving is sex with a woman. We talked about a 3 some early in our relationship but i feel doing so now would only ruin our relationship. I don't know how to feel. I feel awful. Im not going to cheat but its something i want so bad.
