Where can I find the number of UTXOs my receiving address contain ? Is there any website ?

You can see it in your non custodial wallet. Turning on Coin Control feature and you will see more details.

If you use a non custodial wallet, you don't have to check your UTXO with block explorers because they will collect data from you when you visit their explorers, paste your Bitcoin address there.
If you don't want to expose your bitcoin wallet to Internet like a hot wallet, you can import its public address and get a watch-only wallet.

If I reuse an address to receive bitcoin will it count as a second UTXO ?

UTXO, what does it mean?

It is Unspent outputs so if you have bitcoins in your wallet, you have UTXOs. Your wallet UTXO number will only become 0 if you have no bitcoin (no satoshi) in that wallet.
When you receive a first bitcoin transaction in your wallet, you have a first UTXO. Receive a second bitcoin transaction in your wallet, you have a second UTXO.
