Hey Angelcag9, do your thing sister! I am a girl (well.. a grown women now ) and as a teen I liked that car stuff, working along side my brothers and his buddies as much as I loved my cooking-sewing-knitting classes in highschool. But, I knew when to girly-girl up for a date with my boyfriend after a Saturday mornining of greasy-car activities!
Now as a grown women I feel just at home in Macy's as I do Home Depot or Auto Zone. I can shop for clothes or even go to pick a part auto parts shops with the greatest of ease and my husband LOVES that I know a bit more about cars than the average female. Also auto mechanics can not scam me like they can a gal who knows nothing abut the workings of an automobile. P.S. I Iook real girly-girl, with manicure/pedicured nails and a beautiful hairstyle, even when I go to buy auto parts at Auto Zone. Don't listen to lexismith1699 - - YOU CAN BE BOTH!!!
Some guys will like it and others won't, don't worry about it. If you are enjoying it then one day a guy will be okay with it. As for friends, shouldn't be hard to find some that like the same things you do.
