That is a rough situation and outside of the concept of coming out you might want to talk to said friend about the whole thing as a whole. Essentially just to make sure you are both on the same page with things and perhaps draw some lines for the future to make things a bit clearer. As to coming out, you've already started. You've told one person, so you just need to tell another and another and another as it feels right. I wont claim to know you're current situation, and there is a wide spectrum of possibilities depending on where you live, religious affiliations, and so on. But you know the people you are around. Deep down you probably have some idea how they will take things, and it is possible you're brain is causing a conflict. We as humans have a good way of psyching our selves out. Right now it sounds like you aren't in a situation where you are "bringing someone home to meet the family" so to speak so you have some time to test the waters with people. Use current topics or something as a smoke screen or something that is relatable. depending on how resistant or approving someone is might give you a way to get a better feel for their acceptance. If you find you have a lot who aren't you have time to surround yourself with people who are. If they are, then you have time to figure out how to bring it up if you want.

a couple things to keep in mind in all of it. one is that there are differences in behaviors related to the sexes that make things less obvious. Straight women do hold hands for instance, male sports players patting each other on the butt, so on. These things quite often will be overlooked and thus in a relationship situation on your end, wont really play into needing to come out so to speak. Secondly is that its entirely your choice to tell someone or not. Unless you are planning to do overt public displays of affection, people are generally people and no one is going to have a clue. Now sure if you plant a kiss on someone, okay there may be something there, if you introduce someone as your girlfriend or boyfriend, then generally there is an affiliation other than friends but not always. What i am getting at is even if today, you began dating someone and had a relationship, you can have that and absolutely no one have a clue outside of those you live with (potentially). So because you want to come out. I'd look at those you know you can trust who will support you, maybe bring them in on it, and then you can branch out from there, just understand it doesn't stop you from being able to have a relationship at the same time. At most it limits how "public" you are about some elements around those close to you.

I feel bad just know there is always more people. I do not yet have the courage to tell many people and I know it hurts to move on but it is healthy...
