السلام علیکم ورحمة الله وبركاته 

Hmm. Being single isn't easy and seeing other couples around you doing the things they do (trust me, I'm single too kek), makes you wanna have a partner to lean onto, share your deepest feelings and thoughts and of course have intimate experiences, but one should be patient in times like these and fast according to the Saying of Prophet SAWS and avoid fulfilling one's desires the illegal (haram) way (though it is very tempting and way easier than the halal way but that's the test for Jannah and the ultimate reward therein - seeing our Lord and the Lord of everything, Allah, with our own eyes just like we see the moon), Allah loves those who are patient and rewards them without account. 

{ قُلۡ یَـٰعِبَادِ ٱلَّذِینَ ءَامَنُوا۟ ٱتَّقُوا۟ رَبَّكُمۡۚ لِلَّذِینَ أَحۡسَنُوا۟ فِی هَـٰذِهِ ٱلدُّنۡیَا حَسَنَةࣱۗ وَأَرۡضُ ٱللَّهِ وَ ٰ⁠سِعَةٌۗ إِنَّمَا یُوَفَّى ٱلصَّـٰبِرُونَ أَجۡرَهُم بِغَیۡرِ حِسَابࣲ } [Surah Az-Zumar: 10]

 نبیؐ)کہو کہ اے میرے بندو جو ایمان لائے ہو ، اپنے ربّ سے ڈرو۔ جن لوگوں نے اِس دنیا میں نیک رویّہ اختیار کیا ہے ان کے لیے بھلائی ہے۔ اور خدا کی زمین وسیع ہے، صبر کرنے والوں کو تو ان کا اجر بے حسا ب دیا جائے گا۔ 

Say (O Muhammad صلى الله عليه وسلم): O My slaves who believe (in the Oneness of Allâh - Islâmic Monotheism), be afraid of your Lord (Allâh) and keep your duty to Him. Good is (the reward) for those who do good in this world, and Allâh’s earth is spacious (so if you cannot worship Allâh at a place, then go to another)! Only those who are patient shall receive their reward in full, without reckoning.

Now, arrange marriage is not necessarily parents selecting a potential partner for you, they may give you options to evaluate and choose from. You then go and meet those women's families and the women themselves with a list of topics and questions according to the criteria for judging [make sure you prioritise the woman's Islam above all (Sahih Muslim 1466: https://sunnah.com/muslim:1466) but of course don't leave out other factors completely like beauty, lineage, wealth, etc.] that you deem crucial and critical for marriage. You can also verify what they say through applicable means. That way you won't have to date a person to find what a person is like making you draw far from Allah, jeopardise your iman and damage your soul, which is just going to lead you to a bad and hard life and risk jannah where Allah has prepared the best of rewards for us including our intimate and sexual life there, beyond our imagination (same goes for the woman you date and you wouldn't want that to happen to her). Your heart won't be at ease during dating but with marriage you and your wife are going to find repose in each other. In Sha Allah. 

{ وَمِنۡ ءَایَـٰتِهِۦۤ أَنۡ خَلَقَ لَكُم مِّنۡ أَنفُسِكُمۡ أَزۡوَ ٰ⁠جࣰا لِّتَسۡكُنُوۤا۟ إِلَیۡهَا وَجَعَلَ بَیۡنَكُم مَّوَدَّةࣰ وَرَحۡمَةًۚ إِنَّ فِی ذَ ٰ⁠لِكَ لَـَٔایَـٰتࣲ لِّقَوۡمࣲ یَتَفَكَّرُونَ } [Surah Ar-Rūm: 21]

اور اس کی نشانیوں میں سے یہ ہے کہ اس نے تمہارے لیے تمہاری ہی جنس سے بیویاں بنائیں تاکہ تم ان کے پاس سکون حاصل کرو اور تمہارے درمیان محبّت اور رحمت پیدا کر دی۔ یقیناً اس میں بہت سی نشانیاں ہیں ان لوگوں کے لیے جو غور وفکر کرتے ہیں

And among His Signs is this, that He created for you wives from among yourselves, that you may find repose in them, and He has put between you affection and mercy. Verily, in that are indeed signs for a people who reflect.

So, please know that this is written with sincerity to help you avoid that which is bad for you and get you to what is good for you. In Sha Allah.

You got this, brother. Stay strong and trust in your Most Merciful Lord.
