Am I a possesive boyfriend? How can I be open minded?

Me and my girlfriend is in a long distance relationship now. I am stuck in Sydney while she is in Malaysia. We're 4500 miles apart and I miss her every single day. We do update each other about each other's life.

I'll text her when she's not having class, unless she text me during her class. I'll only give her a call after she finish her class about 5pm and call her when i sense that she's unhappy or frustrated. Well, basically everything is fine, except the fact that I think I am a jealous freak.

She's doing a medical ultrasound course. Well, that's scanning patients. In the learning process, she and her friends have to scan each other to practice, scanning abdomens, thyroid and stuff. I am constantly worry that she'll need to undress herself to be scan. Initially, I am okay with it since her batch of students were made up of 9 girls, including her. Until 2 days ago, a guy just joint.

This is where the problem starts. She told me that, in a months time, they will need to learn breast ultrasound. Initially, both of us thought that it's just protocol teaching. But her seniors told her, everyone will need to undress and to be scan by each other.This meant that she'll need to undress her top and let that random guy scan her breast. When I heard, I just can't help but to feel depress, very very depress. She's my girlfriend and I don't anyone to touch her. Especially, her breast.

This is the breast ultrasound protocol that will be carried out: (

One thing that might help you? I doubt the guy will be allowed to ultrasound the individual women, just the two of them in private? There will be other women there and/or the teacher, etc.? Too, the machine will be on her breasts, not the guy's hands and he'll have to be looking at the monitor, not her breasts to see what he's supposed to be looking at/for.

However, I also kind of doubt that 9 women and a guy are all going to get naked and all do each other; there will probably be "pairs" or each person will have to do 2-3 others or something; it would be too long/complicated a lesson to have everyone doing everyone else and it could be the guy will be treated differently or will have other partners than your girlfriend, etc.
