so like, you have A addess (your electrum wallet), and then you send to B, C, D, etc? then it would be obvious that B to D got some tx from wallet A. as mentioned above, you need mixer or coinjoin to obfuscate your txs.
You mixed addresses and wallets in your reply. If you have coins in address A, as soon as you send from address A to Receiver B, the remaining balance from address A (if there is any) will go to change address X. They won's stay on your address A. Your address X doesn't necessarily have to be linked with address A and be identifiable to belong to the same wallet. It could be seen as a change address or a second receiver.
