Done Whats this タマ please?

[LuckyBlue]

Hi there >< sorry it's me again.
These are contexts form some naughty scences. It's not normal at all. It got many タマ in there and which I couldn't find a right meaning...to suit the context. I'm looking for help thank you!!
キミ「タマブラブラさせて」事じゃね
いいじゃねかいつも「タマの裹」までみてるくせに

タマ=nuts,balls,testicles
Other things I can't imagine in those lines.

@OKfarm Thank you a lot for this trying to help. I don't know how to edit this thread after posted them.
Really sorry. This is the whole context. 2 men talking to each other in a home-clinic. I'm not sure how much that I can post about this kind of conversation.
Thank you in advance.

1) AV女優見ると勃起してても垂れてて突いてるときもブラン... ... 通常時もあまり垂れません。その前からです「タマ」は寒い時期以外常に「ブラブラさせて」ます
2) キミ「タマブラブラさせて」診察室歩くんんじゃねぇ
3) いいじゃねかいつも「タマの裹」までみてるくせに
4) 心配すんな決めてくれる女ならいくらでもいる
