Hello Katia06
I'm not one for giving the advice here but sometimes I read something and like to add a few of my own words.....I can only go on what you've wrote plus I don't know you so I can only try to write what I can here, I don't know if it can help or anything, hope what I write makes sense...
...Your 22 and as time moves on ,you change ,develop as a woman and experiences and relationships and 'life' shapes you. You mix around people who you can really be yourself with..and eventually you may grow comfortable, perhaps you won't ever get to the stage of feeling comfortable but for whatever reason...it won't bother you and you will find your 'niche'.
I don't know if this bit will address how your feeling ......but I think when you do get more comfy with your sexuality..you notice how alot is geared towards hetrosexuality..but that's just what I felt/feel..
best of luck and like the above post says..."It's a confidence thing".
just be yourself, things will happen when they're ready.
take care
Ms K
