When to reveal certain things?

So I have a couple of questions regarding when/if to reveal certain things about myself.

(#1) I had a lot of hearing problems when I was born and had to have tubes put in my ears twice when I was very young, so I wasn't able to hear properly until I was about 4. I ended up going through several years of speech therapy because of it, and I still have hang-ups about the way I pronounce certain words and stuff., plus neither of my parents are originally from Texas(where I grew up and currently live). So I have often gotten questions about my accent, and the way I speak. I have once also been told by someone that they thought I was slow when they first met me, and the way some people respond/look at me makes me wonder if they think the same thing. I guess my question is: Should I mention something about my early hearing problems early on with potential matches, or just wait and see if it comes up in conversation?

(#2) This is also about revealing something about myself, but completely unrelated to the first question. I tend to find myself mostly attracted to white guys, and would rather marry a white guy, but more because of cultural reasons, and I just tend to get along better with a white guy, but I have had some "experiences" with a couple of black guys, and I wonder if that's a turn-off/deal-breaker for some guys and is it something I should mention? I know my sexual history is MY history, and not up for display to others, but is that in particular something I should reveal or not? I don't have a problem telling a guy that I am experienced, but to what degree and when?

1. I wouldn't bring the accent/pronunciation up. What purpose will it serve? Maybe other people's looks (at you) have nothing to do with your speech. Also, Texans question everyone who don't speak like a Texan. Everyone will have their own perception. Avoid the power of suggestion.

2. In your reference to having "experiences"... could you be more specific? What you mean by "experiences"? One night stands, flings, FWB, relationships? Why would you want to tell a new interest this? What purpose would it serve? I also wouldn't tell someone you are "experienced", it comes off as bragging.

I would probably mention the hearing/speech/accent thing very early on to put your match at ease since they may very well have a question about it but be too embarrassed/polite to ask. I would do this either before or during the first meet and/or phone call. Just make sure to talk about it in a matter-of-fact, light-hearted way (maybe even joke about it) so that they know you're okay with it and that you're not "slow."

As for who you've dated and been with in the past, I don't see any reason for that to ever come up ever unless you WANT to disclose it for some reason. If a guy you're dating is racist and you have a problem with that, you should call it off then and still have no reason to disclose who you've slept with in the past.

If your accent is obvious then your match / date will most likely mention it and you can then say something about your background with respect to your accent. If you have trouble hearing now then you should reveal this before first meeting. If you need you date to speak louder just ask them and don't feel badly if you have to ask them to repeat something. If your hearing is fine now and the problems were only in your childhood then there is no need to bring it up until later and then it is just a story not a problem.

I don't think that this is information that you need to volunteer. If asked about your relationship history you should be honest with your answer. An honest answer could also be "that is none of your business" or "it is too early in our relationship for this conversation".
