Why do you think you are a loser? Despite that, what do you mean by loser?
Just because you get rejected it doesn't mean you are a loser, maybe the women who reject you are losers, because they don't know to value the right thing on a person or have wrong understanding, standards?
Even if you are a loser, doesn't mean you have to be a loser for ever. Despite the fact, that I am sure you're not a loser. Became a man. We all have to work on our selves. If you have some character issues, work on them. If you have not good education, work on that. If you have no money, find a job. If you think you're ugly (there is nothing like that, finding someone attractive is something subjective), get a nice hair cut, wear some clean good looking clothes, take care of your self and you will be fine, inshaAllah.
I am at a similar situation, apart from I don't get rejected because I simply don't know anyone to marry. The pressure we're in is the same and shaitan whispers weird stuff. Don't commit Zina. Don't pay for this thing!!! Eudhubillah. Just think on how you would feel afterwards. You would have the title of a zania, for all you life.
Allah says:
{وَالَّذِينَ هُمْ لِفُرُوجِهِمْ حَافِظُونَ إِلَّا عَلَىٰ أَزْوَاجِهِمْ أَوْ مَا مَلَكَتْ أَيْمَانُهُمْ فَإِنَّهُمْ غَيْرُ مَلُومِينَ مَنِ ابْتَغَىٰ وَرَاءَ ذَٰلِكَ فَأُولَٰئِكَ هُمُ الْعَادُونَ} Quran 23:5-7
"And they who guard their private parts. Except from their wives or those their right hands possess, for indeed, they will not be blamed. But whoever seeks beyond that, then those are the transgressors."
Do you know what will happen with those you safe themselves from that evil? Allah says a couple ayats later:
ُ{ولَٰئِكَ هُمُ الْوَارِثُونَ الَّذِينَ يَرِثُونَ الْفِرْدَوْسَ هُمْ فِيهَا خَالِدُونَ} Quran: 23:10-11
"Those are the inheritors. Who will inherit al-Firdaus. They will abide therein eternally."
Read the first 11 Ayat from Surah Mu'minun:
https://quran.com/23 - RasulAllah :saws1: says, the one who commits to the first eleven Ayat of this Surah is most likely to enter paradise. Just consider that. All these things mentions in this range of Ayahs are actually all important to protect society. Don't be of those you don't consider. Just think about all the illness that it transferred due to illegal intercourse.
I don't recommend the following to you, however, there are scholars who permit to masturbate when you are really really close to zina. The best is to not do both, but before committing adultery.... stay steadfast and learn the religion. Masturbation is dangerous, too.
May Allah protect me and you from such evil.
