Am i a lesbian? what should i do?

It's better for both of you to be honest about it. If he's to be dumped by you he deserves to know why.
I suggest talking to him about it because he deserves to be with someone who finds him attractive ...

So there is no problem with him. It's all in your mind. Don't rush into anything. If you make a special girl friend, you may find that actually licking snatch is much different than you have imagined it to be, and then you might start fantasizing about men again.

Just keep giving your husband regular sex for now. It will take time and effort for your mind to work thru all of this.

Being lesbian is nothing to be ashamed about. It is accepted in many societies, only those who are so soaked up in religion and are so persuaded by the misinterpretations from the bible about gayness being unacceptable will say otherwise. If you have no feeling for your partner then please do not lead him to believe that you still do. Worst case scenario is that things such as marriage and kids can be involved and that is unfair. You need to tell him what you feel, if he loves you he should understand, it will upset him to know this, and although it may make him think he is no good in the bedroom etc, you have to ensure him that, that isn't the reason. Your feelings about women will remain, especially if your feelings for your partner have gone. You need to explain to him and end it now before you hurt him more. Then you can go and explore the things you desire.
All the best, I hope this helps you.

You need to explore these fantasies, even if it means leaving him. Suppressing them will not make them go away. If anything, they will grow stronger, and you'll probably end up cheating on him. Why stay in a relationship that you're not happy with, honestly?

I think other people have covered the bulk of the stuff stuff but i'd like to add, you can be attracted to someone in many ways.
Physicialy, sexually, romantically for example...
And your romantic and sexual orientation do not need to line up (like me; i'm an asexual but homoromantic).

Potentially, you may be bi/heteroromantic, as you may feel relationships wiht men are good, but may be homosexual. Potentially, of course. If i were you, i'd see if your thoughts carry on over a long period of time and if you still feel this way in the future, then i'd veyr much consider being lesbian.

There is a different with being "in love" with someone and just loving them as a person who you care for like a friend.

Many straight women can find other women attractive without there being a sexual attraction there. Equally lesbians can find men attractive but not be attracted to them. It's human nature to admire things that we see as beautiful...

Also there is a difference between having a girlfriend and just having sex with a women. It sounds like you want to experiment and explore what it's like with a woman which is ok and sounds like you should probably go out there and do it.

Try not to get caught up with labels and don't beat yourself up for having these thoughts.

you say you love him with that said you can only tell him the truth. honestly If you truly love and care for him you have to come clean and tell the cold hard truth. If this was twisted and he was gay and you were still interested in him you would wanna know RIGHT??
