Preflop
This is way to wide UTG. You need at least a hand like T9s to get involved here, and then you should raise rather than limp-call.
Flop
I dont like leading AKA "donk betting" here. The problem is, all better hands call or raise, and most worse hands fold except for good draws, that have a lot of equity. So its like asking the opponents "hey would you like to play perfect?" You should not be in this hand, but lets say you got a good price to defend your big blind and saw this flop 3-ways. Then the play is to check and call a reasonable bet from either opponent. This allow them to bluff and keep their range wider.
Turn
You picked up a flushdraw, but you already have a made hand, and its difficult to get many worse hands to call, if you bet again. So the play here is still to check and call. You do bet though, and now the opponent jam. This is now a pure math decision, and its somewhat close. You need around 20% equity to call, and on an unpaired board you would easily have that. But when the top card has paired, you cant beat a J by hitting a T or 6, and you can only beat an overpair by hitting a T. Or of course a flush card. Finally there is also a small risk, you could be drawing complete dead against JT or have just 4 outs against 44. But on the other side there is also a small chance, you are actually ahead of a hand like KQ or 98. So having dug yourself this deep in, I think, it is a small mistake to fold now.
