I am a bisexual guy dating a bisexual girl so take these answers with that in mind.
1. If they ask, just say it, if they can't handle it then you don't want to be with them anyway. That said, no need to go yelling it if you aren't asked. What matters is whether or not you are attracted to *them* not which gender(s) you are attracted to.
2. Nice to know, but if it was on a first date I'd be curious why they found it important to tell me without me asking.
3. Is it wrong to be short? tall? white? black?
