Have you talked to a therapist , or your doctor about your rape ?
If not then my advice is before you go looking for love you need to talk to someone and heel from the pain you experience .
It's very hard to get that " spark" from another person so if you get it hold on to it even if your scared .

If you find the right guy then you can tell him about your past and how you feel .
Being scared sucks but if you want something bad enough you will blaze threw it and you just might find the guy of your dreams .

Another thing is maybe it's not fear you feel it's butterflys when you meet someone they feel the same .
