I know that feel, brah. Im one of the six engineering girls at my uni. Ugh. Nasty guy jokes are becoming the norm for me, and most of my friends are guys.

Op, think of it as a good deed you're doing. It has been scientifically proven than staring at boobs is good for your health. True story.

Learn to laugh a bit? I was in technologies and I was the only female in a group of guys. If I caught them staring at my boobs I'd call them out on it in a silly fashion, ie "oh hey, and I always thought my eyes were on my face!" or "you seem awfully fascinated with my shirt... Are you wondering if they have it in your size?". Guys, especially younger guys tend to be a bit hormone driven. Nothing personal, and half the time they aren't even conscious of it. If you relax and have fun a bit, you will probably find a whole group of very loyal friends. Geeks can be a bit awkward, but when the chips are down they are there for you.

Hurray for teh gay!

Congrats on the schooling choice, but regardless of intelligence guys will be guys. The novelty of your particular set of boobs will wear off soon enough and they will be more interested in what you bring to the table as far as your mind.

The sacks of fat strike again

Actually, if they are good engineering students, they are actually looking at your boobs and figuring mass vs. distribution, load factors and support. All important when trying to build bridges, tall buildings, support structures,etc... Or they could just be staring at your nipples pointing at them.

The joys of being an engineer... I know how you feel.

U must have a nice rack

Buncha dudes with Raging hormones, can ya blame em?
