I suppose that before you start worrying about what other women would think of you, start with figuring out what YOU want. If you are not actively dating because you are afraid of what they will think, that is one thing. However, if you are not dating because you don't think that you are ready, then that is completely different. Figure out if you want to date or not before anything else.
Now, if you do want to get out and start dating again, don't think about anyone else right now, just do it. One of the things that I think is really sad about modern times is the idea that if you go on a date, you are then committed to a long term, deep, heavy relationship. 20, 30 years ago it was accepted that people would date a few different people, non-sexually of course, and didn't feel committed to anyone for a while. Try this; there are, believe it or not, sane women who don't need a promise of marriage on the first date. Let the women know that you are just looking for a casual dating experience, and this will scare away the ones who might put pressure on you. See how it all goes and if you can handle it at the moment. I don't see any reason why you would need to bring your past up at first, unless you find it is still in the way of your ability to function.
If you date for a while and find it too difficult, there is nothing wrong with taking yourself out of the dating scene for a while. Perhaps it would be a better idea to cultivate some good friendships with women that you think are worthy of friendship, and take it really slow. I have found that relationships that started with a friendship ended up much better than dating immediately. I would strongly suggest staying away from a sexual relationship unless/until you know that you are really comfortable with the intimacy that goes along with it.
You are young, so give yourself some time. Take care of yourself, and it will all work out. I don't know you personally, but the gals here hold you in high regard, so that must say something about your character. Good luck, and if you make your way out to California......
