Sex between lovers should be an act of love. You should not be forced into it, nor he be deprived of it. But in your case, he must be more supportive and understanding and not give you conditions. Having experienced the same situation, healing takes a while, I am still in the process, too.

Are you having counseling to deal with it? You should seek help as soon as possible. Regarding your BF, you should be glad he's shown you his true colors early on. Based on what you've shared, he will eventually end up forcing you to it and again, you will have to deal with ABUSE of some sort.

Show him the door. You need relationships but it shouldn't be romantic yet. Friends are always around to cheer you up....hey, we're here!
