<human>: Can you give me the gist of the text in a nutshell?

So, I'm 22 with the style of a grandmother and the face of a 15 year old.  I like florals, big glasses, knitted things.  I make pretty good brownies and can cook pretty well.  I'm very 'domestic' in my hobbies, laugh at everything, and get pretty nervous about sexuality (can't bring myself to look at porn for instance, it squicks me out).  

Now, I like who I am as a person, but I wish I could feel 'sexy' rather than cute.  Not just for my boyfriend (22M, 3 years) but for myself.  My boyfriend doesn't mind how I act, but I really wish I could have the kind of sexy confidence that some women seem to have.  I act like a stuffed animal if I feel 'in the mood', or I try to be cute and make hints (which don't work), and if I try to be more grown up it just doesn't work.  I want to improve my sex life with my boyfriend, because it's gotten dull and part of the reason for that is because I don't feel sexy, and I want to learn to feel that way.

Now, the reason I didn't post this to the sex sub is because there's another aspect to this too.  I'm not really taken seriously by other people sometimes, especially potential friends.  Could my clothes be at fault?  My lack of interest in pop culture/nerd culture?  I tend to connect best with people either way older or way younger than me, but I'd like to find some friends my own age, mainly college kids.
<bot>: I don't know to act sexy for my boyfriend and it's affecting our sex life, nor do I know how to make friends with people my own age.  Any advice on these would be great!
