when i was going out with my girlfriend... ex girlfriend but this is besides the point.
We were togeahter for a year and a half.
She never took off her top its might just be a hole breast thing. She might be just insecure about her size . I dont think its weired at all.
Good luck man!

I had quite a phobia of being seen naked as a teen. When I lost my virginity to this wonderful girl she disrobed in front of me while I got under the sheets and removed all but my underwear.

I think that if she had any reservations about my honesty, as I had told her I was a virgin earlier,  they were dispeled by my unusual behavior.  She remained in her panty hose but was otherwise naked herself. I think she wanted to bargin that if I'd remove mine she would remove hers.  We cuddled and kissed and enjoyed the feel of her lovely breast in the youthfull hairiness of  of my chest.  She could feel my erection against her and wanted to touch me. I had already touched her plenty.  Then she began to ask if she could see my cock and I rather reluctantly allowed her to pull off my shorts.  

Before she did anything else she placed her arms around my neck and kissed me thanking me for overcoming my fears. Then she subtly raised her thigh into my balls and drug it up under me.  I almost came from the feel of her nylons doing that.  She giggled and asked if I liked it.  Then she told me that there would be many more good feelings to come with the sex we would have.  She was so right about that.

She got out of bed  and stood with her back to me and asked me to sit on the side of the bed and pull down her stockings.  I did so having not been this close and personal with a girl before.  Then she turned around to reveal herself to me completely and reached for me to stand up and embrace her. Of course my erection was in the way a bit but she told me she had just the place to put it so we could press ourselves together.  I'll allow you to imagine the rest.

If you have issues Kate, with your breast size or anything like that....try to talk to him to help be supportive in getting over them. I was very lucky with the girl I shared my virginity with
and she made my first experience a positive and constructive one.  You can build yours the same.

If breast size is an issue, try to remember a lot of girls don't have very large breast when they are virgins, but with sexual activity the hormones begin to awaken and change that awkward condition.  The female body is geared up for reproduction with sexual activity I'm told and it brings forth
a more womanly body.  So perhaps good things may happen for you and give you reason not to hide yourself.

I can only guess.
