Honestly, Tommy isn't sure. But if he had to pick one...

"I don't know. I guess it's just weird that you're concerned. Or maybe it's weird that you'd think I'd let it happen. Because I wouldn't. And I don't think he'd actually hit me, if I liked him. But it might destroy our friendship. And that I can't... I don't want that."

And that's something that he felt like kept getting brushed off. Sorta a 'if you lose them then did he care'? And Tommy thinks it would be more like 'you'd lose him because he's afraid that the only reason you care is for his body'. Which isn't true. Even if it's a nice body.
