I think that you need to talk to your partner about how you feel about you in a relationship with him and talk about expressing feelings, care, attitude towards you, so that you both feel comfortable. I don't think you have any problems with gender identification , but if you are very worried about it, then here Gender Role Test you can find a fairly accurate and definitely interesting result. I also want to remind you that you don't have to adapt to someone and you are able to make your own decisions.
