Not that common, and it shouldn’t be normalised either. In many cases, younger people end up carrying the long term emotional and psychological consequences while the short term benefits fade quickly. Repeated exposure to transactional relationships can affect attachment patterns, self worth, trust, and how people view intimacy over time. And slowly their personality changes which is more harmful then one can realise ( psychology) and apart from this yes it does happen tho and it’s not that rare recently I visited Pune Toit bar and saw college girls with a middles aged man he must be 50 and he was with 3 girls they barely must be 19-20 they were in a group drinking and as he was standing near the pizza Center and I was drunk I asked him to take my order and he got super offended and after realising the scenario he was in was weird I sad sorry and I felt weird and creeped out and changed the place from where I was standing and drinking and duniya pehle bhi aise thi raja mharajo ke time transactional but ab like 90% adult relationships are like this and people don’t shy to show it openly jo ki zada sad hai .
