No this is not strange. That is who you are! Stay who you want to be and do not change for anyone, if you like wearing jeans wear them. Also playing video games all the time is probably not healthy, but it is ok to play them a little more than going out with friends. I am totally the same, I love jeans and sweatpants, and also hangout with my family more than friends, and I have had boyfriends. Just stay who you are, and that one guy that loves you for who you are and not what you have on or what you like to do in spare time will come along and probably even share some of the same things as you do.
Hope this helps you some!
