Welcome my friend. Some suggestions:

– Left side menu could do with larger fonts.

– Logo needs to be linked to root page / home (important navigation element that many people use) on your adult tube.

– More space! Everything is squeezed together, one of the most important elements in design is empty space. Specially here with products. None of them actually seem to fit in.

– Less clutter and objects. There are too many things going on, to many products, links, navigation items, options. It can possibly be a bit overwhelming. Maybe you are trying to give people too much options?

– Font Colour on prices wrong maybe? Red is often associated with “Sale” and might work better. Not sure prices should be the largest text on the page. If you are not cheaper than everyone else it might just highlight the fact even more.

– Mix of font alignment – there are left, right and centred text, no consistency. Better to stick to one of the 3, probably all text left aligned.

– The menu (login) on the posts seems pointless and does not work with the page very well. It is easily missed and the options on that menu is already available on the left side navigation column. Why double it up? It just adds to the clutter and does not actually stand out as a real menu.

Just a few pointers, do not take it the wrong way as personally I find that critical advice is better than praise.

I think you should buy another WordPress theme for your site. You can google “WordPress Membership Theme” or just use some other free theme. Make sure you go to paysite review sites like rabbitsreviews.com and check out the top adult sites to see how to change your website.
