Well, you have two choices:

1. Never persue it. If she ends up getting a bf and taking to you about their relationship physical and otherwise, would that make you jealous? Or you good with that?
2. Going for a romantic relationship with a best friend usually ends one of two ways: together forever, or no longer friends. There is also a small chance you could either still be friends afterwards or you found a rare opportunity for a casual relationship.

Hard to tell. GL either way.

Could very well be. If so, lucky you.

Massage, see my tattoo (and letting you pull her hoodie up/pants down), and I'm sure she noticed the boob swipe but didn't say anything.

But, up to you if you want to risk sabotaging that bf relationship.

Dude, I read this as just several paragraphs of signals. Do they know you're straight or just don't believe you?
