Hi and welcome. Yes, some of it is the profile. The good news is that the issues are all easy to fix. Semi-standard disclaimer: Even if what people say sounds mean, that's not the purpose of their comments. Instead, that's to make it easier to find who and what you want so as to have all the sex you have time for.
First, your photos. As has been mentioned, those body part pics of her aren't a good look. At the very least, they will never attract another woman. We have our own body parts and are pretty unimpressed by anything less than the whole woman. Bonus points for being well dressed and obviously happy and friendly. Maybe go for fewer photos, too. Velma is the real photo maven, but she's away at a conference and may not chime in. If she doesn't, you can find many examples of her excellent advice on numbers and composition of photos.
As far as the profile, your tagline is meh but you're new so it's fine. Just capitalize the first letter and be sure to change it after your first experience. Also, your toggles are currently set to Want Drinkers/Want Smokers, which is one of SLS's fine gifts to its members. Every single time you change your profile and get the changes approved, the system sets your toggles to the combo very few of us want. You have to go in and change them manually, doing nothing else (not one thing or the whole mishegas process starts over).
In Looking For, I'm confused. I think you want to meet with a single woman (not female, please) or the female half (see the grammatical difference?) of a couple for an FMF and then have the male half of the couple join in. For what? That's the confusing part. You've toggled for very little interest in full swap and I'm probably not the only one to scratch her head on reading this.
Anyway, the section needs more anyway, even after you've come up with different words for what you already have. Who are you looking for, what you want to do with them, etc., are questions to answer in this category.
In Description, the Him/Her thing is clunky. Just try whole sentences starting with He and She and not very many of them, because this is about the we of being a couple. The information about having a kinky side or fantasizing about FMF/FF belongs in Fantasies. The portions relating to his tongue and her oral skills belongs nowhere here. When you get a chance, do (don't tell) the things and let your certs talk about the specifics. Seriously, you're expected to be good at these things and there's no reason to highlight them and a bunch to not do so (including that women generally view claims of being orally gifted as code for "he can't always get it up"). Tell people about who you are. What do you like, what will we talk about, what sort of hobbies do you have? I know it's counter-intuitive to focus on non-sexual things on a swingers site, but those of us looking at your profile can fuck anyone, pretty much, and many of us are looking for people we can fuck with whom we can at least have a tenuous connection.
In Fantasies, I've suggested things to add to what you have. You might also include "or woman" to that sentence.
Additional comments is a no. You have single men blocked, so you needn't mention them and it's an error to end on a negative thought. So, something fun here, maybe.
Anyway, I'm hoping you spend some time reworking your profile and then come back and let us see what you've done.
Good luck!
