Where to find new sex tips/tricks online?

I recently started seeing this new girl who isn’t the most experienced sexually. A ton of the advice on here is about communication, but I found out early on she really doesn’t know what she likes until I try it. I’ve always been able to make her come via oral, but struggled with penetration.

I can find plenty of sites that have a bunch of different positions but struggle to find many thorough sexual education sites to give me new strategies for positions/oral/general tips etc.

Any and all help is greatly appreciated!
