Pre you need to raise larger, 60 is the absolute minimum you should raise here but I would advocate for 75-90.
Flop is interesting because at first glance I'm thinking a young thinking reg would likely raise here with sets, 2p and some backdoor combo draws. And yes, v will show up with these when your raise size is so small and he's getting incredible odds to call. However, your flop sizing looks weak I think, the board is not textured but you do have the entire table to act behind, and v may be making moves based on this alone. Your line should be to bet larger here 3/4 or pot because of how many players involved I think.
Turn is a call, sure his bluffs get there and his sets remain nutted but you need to call off when you call flop and improve turn.
