I pretty much agree with the advice you've already received. You might want to try composing your text in a word processor on a computer and run both spell check and grammar check on it before pasting the text into your profile on SLS.
In Looking for I'd delete both the line about women over 30 (change youngest Desired Age from 18 to 30 instead) and the line about good email and pictures available.
In Description I'd delete both the line about being straight Asian guy and about average build with few extra pound. Add a few lines about what you like to do for fun. It looks like you enjoy sightseeing and sports - include that as well as anything else that might indicate common interests with couples and ladies you hope to meet. Things like such as cooking, enjoying movies or ballroom dancing.
In Fantasies I'd delete the line about spending time with elder ladies - you've already addressed that by changing your Desired Age to 30. And as MsMolly mentioned change the last line to "would like to participate" and leave off the info in parentheses. I assume you mean gangbang but you might want to spell it out rather than abbreviate - you already have a problem of being possibly misunderstood so don't make anyone guess at what you mean.
Additional Comments should not be left blank so maybe this is where you should state that English is not your native language and maybe where you are from originally.
Your current pictures are OK - not great but I've seen worse. An full length picture dressed for a casual date (nice jeans & polo shirt or dress slacks and dress shirt) should be the next thing to add. In a private gallery you might want to add a few smiling face pictures that you open when you initially contact someone (and let them know you opened your pictures) or when someone contacts you. You always want to smile, watch for messy distractions in the background and avoid selfies.
Good luck!
