Hey there, Simon66.
I think that if you go through with this procedure, you really need to do it for yourself. If a guy is going to judge you on how you look or expect you to change to fit some mold that he finds attractive - that's totally HIS issue. You are worthy and deserve more than that... don't settle and don't sell yourself short. I don't mean that to sound preachy at all, just saying no guy is worth jumping over hoops for. The right guy will love you for your heart... and yes, there has to be attraction and everyone is attracted to different things. I've had guys who didn't give me the time of day when I was 350 pound who now try to talk to me... on the flip side - I've had bears who found me hot then a bit dismal now. And ya know, that's fine. lol
I, personally, had this surgery done for health reasons and for the fact that I want to be around as long as possible. I am down to the low 190s and I feel amazing. I have a confidence in myself that I wasn't expecting. I find the biggest changes and epiphanies are all the things that weren't on my radar when I began this journey. Since surgery, I've been taken off all my meds (8) and have plenty of energy. Yes, there is a little extra skin but it doesn't bother me at this time... and perhaps in the future, I may choose to do something about it. But if I do, I'll do it for me. I think I'd rather get some new clothes or save for a car tho... lol.
I also had a rounded and full face... I still look younger than my 47 years but yes, I do notice a difference but again, no complaints. I guess the bottom line when I think of it is... it's all gonna fade in time. It wasn't the reason for me. I had been on diets for 30 years... and like you, I would lose a good amount of weight and then turn around and put it back on and then some. I needed a permanent restriction. This has worked for me so far.
This is not an easy thing... if you do this, make sure it's for the right reasons. There is no going back and it is a life changing thing. I don't regret it for a moment and would do it a thousand times over. I have my life back.
Someone WILL like you regardless... you just have to be patient until you meet. My advice is... focus on you. What makes YOU happy, what YOU want to manifest and when people see you doing that... see you happy in your skin... that is sexy. That will catch the lucky guys eye and he will be lucky to get to know you. Don't settle. Do your thing... everything else will fall into place.
