Sex questions

So 2 yrs ago or so I was I guess raped by another girl for a couple months and since then I've been scared to have/think of having sex with anyone cause I thought I'd have flashbacks or something and last yr I started liking this guy so I'd start having sex dreams about him and everything and I don't like him anymore and around that time I started noticing that I have been almost craving sex but I've never had it? Can anyone help me?
