Christian, virgin struggling with it all now :-(

I'm a female virgin, 40 year old Christian and I'm really struggling to save myself for marriage. I recently met a couple of Christian men from a dating site - all 3 of them are engaging in sex before marriage, some are even on stage at their Church singing then having sex with women from dating apps during the week. It didn't work with me as I wouldn't do sexual things with them - however I'm REALLY struggling now. I was 50/50 to have/do oral sex with these guys as I am FED UP of waiting. I feel forsaken and forgotten by God. Would it really be that bad/big deal/sin to have sex/do sexual things with these guys? It's beyond a joke and I am A 40 YEAR OLD VIRGIN NOW...I NEVER THOUGHT I WOULD STILL BE SINGLE AT THIS AGE....God has not 'blessed' me for doing it his way...I'M REALLY STRUGGLING as I am only human and I am craving sexual/physical touch and pleasure with a man now. PLEASE HELP I'm feeling very hopeless like I will never meet anyone but I really need sex and have little way of releasing the built up waiting/feelings. I am quite low and crying myself to sleep. I even started crying around the food store the other day as I'm so lonely without a partner too - plus I'm burning with passion.
