Does living in my head affect my sexuality?

You may be around boring men. If you are gay that's cool but you might need more exciting guys. Like would you be turned on by a guy that embraced your femininity. I love to smell a girls hair and message her neck and soak in every part of her femininity cause it a a huge turn on. If all the guys you met are just boring and don't show enough affection of coarse you will question your sexuality. Try going out with a guy who is totally turned on by everything feminine and female about you. This will also make you feel good about being desirable to guys.

Not really. Lots of people have homosexual inclination in their minds but they don't seem to get out there and enjoy them. I generally behavior as the strongest statement of preference.

Perhaps some tea. And perhaps a biscuit?

Start dating. Other people get you out of your head and into our world, where you should be spending a bit more time.

You seem like you have a tendency to obsess about things...it is not healthy in general.
Try to get out more.

Abrupt introversion can affect your sanity.

To stop living in your head, just go out and do things, keep busy, meet people, have fun. Sexuality isn't really something you discover through trial and error, as it is something you experience and pursue. If you like someone, regardless of the gender, go for it, or else you might ignorantly decide you don't like one gender, when in actuality you might meet someone of that gender you really do like.

there's nothing wrong with being undecided or queer.
Its a good thing that you preoccupy yourself with other things.
Wait for a person who also shows interest in you apart from kissing.
I dated a girl last year after being undecided for a long while.
Now I'm with my boyfriend.
i embrace my bisexuality
i encourage you to embrace your lack of decision
its about the person, not what's between theirl legs or on their chest.

I'm bi with a tendency towards boys--I didn't obsess about it, kind of found out quite accidentally --was great and I adored being with the girl. But I want relationships with men and when I am in one I am monogamous (no three way relationships). I love the intimacy of one on one relationships because of the intimacy and how special the bond feels. I haven't been with a woman in years since marriage either and don't miss it per se but I still admire feminine beauty--you will learn the more you interact--thinking about the possibilities is not as great as sampling them...

it could be a fantasy.. myself.. I have at times debated.. but once I finally hooked up with a girl and did all I wanted.. I realized.. I'm straight. lol so just do what you can to find out.. but as long as its only in your head you will never know the answer.

you do need to go out, go out with friends family like your siblings. go bowling, go to the movies, ice skating, something active. maybe horseback riding, get a gym membership. exercise your stress away.

your obsessing sounds like it's already unhealthy, if you feel that this determining your sexuality is a problem worth obsessing over, you might want to seek counseling and talk with a counselor about it.

you need to occupy your mind with other things

Most people, whether they want to admit it or not, fall somewhere in the gray area b/t gay and straight. It is rare for someone to be 100% gay or 100% straight, though of course one tends to gravitate either to the left or to the right. But does it really matter? When you meet the right person, gender will become irrelevent. I think your main problem is sexual frustration--in other words, you desire a relationship and it's just not happening for you right now, probably because you are too busy obsessing over whether you want a boyfriend or a girlfriend. What I suggest is to get more in tune with yourself and your sexuality. Sexual satisfaction has two components, the physical and the emotional--you don't need another person to be physically satisfied. So getting the physical stuff out of the way will allow you to think more clearly about the emotional side of things, particularly, if there is someone you know who is compatible with you, gender aside. The reason you didn't feel so hung up and confused about your sexual orientation while your siblings were visiting was because you were distracted with LIFE, as you should be. Continue to be distracted with life. You will only meet someone if you stop overthinking.

It won't be affecting anything, but try to stop thinking about it. There's no need. You either are or you aren't. And just by thinking about it isn't going to help you. :) I would know. It seems like you don't really care either way, so if the situation arises, you won't feel weird about it.

All you have to do if one thing. Ask yourself; does the idea of being with a girl turn you off? Does a guy? There lies your answer. Problem solved. And just like with anyone, you're not going to be attracted to everyone! I'm bi, and I don't like all guys, or all girls. Once you're decided, that's it. Nothing left to think about. And you can always change your mind later one! You don't have to be lesbian for all your life, if you suddenly decide guys are decent. :P

Just get out, meet people, and see what happens! :D
