What Should I Label Myself As When Coming Out?

Hi, so I'm a teenage male who has yet to come out to his slightly homophobic father. I've been confused about my sexuality for a while now, so I've been wondering what I should "label" it. I personally believe that labels aren't healthy or necessary, but in this case it is necessary: I need to either tell my father that I'm bisexual or gay. It seems as if I'm sexually attracted to most men and only sexually attracted to some/certain women, and romantically attracted to both, but I can never be so sure. I've had thoughts about kissing both, and get turned on by both gay and lesbian entertainment. The thing is, though, I never imagine myself settling down and marrying a woman; I always picture a man, so this would probably subconsciously make me seek out male partners instead of females--even though I may be attracted to them, if that makes any sense. This could probably be broken down into the a combination of sexual and romantic orientation, but the sad fact is that I need an easy, simple label to come out to my dad as that he would understand and just maybe accept. I'm afraid to come out as gay because--well, my dad's pretty homophobic. Maybe telling him that I'm bisexual is better, as also being attracted to females might redeem the "gay" side of me in his eyes or some crap, but then again if I come out as bisexual he might expect me to marry and settle down with a woman and have a "proper family," because he thinks that I have the capacity to do so, being bisexual. So, given all this, what should I come out as: gay or bisexual? Thanks in advance!
