I consider myself to be bisexual and I do find both genders arousing but romantically I have no interest in either gender, is there a name for this just wondering.
Yes there is, it's aromantic bisexual. Remember, though, that it's not proven that there's a distinction between sexual and romantic orientation.
If this persists, then you being aromantic is indeed a possibility. That said, remember that you are young. Some people only start having romantic feelings when they're 20 or so. You might just not have started that journey yet. And maybe it will never start, in which case aromantic works as a label. Hope that helps! x
