I'm in a similar situation (32M). I can help a bit, but I haven't figured everything out.
There's a book that I've been reading just to get an idea of how things work and what's "normal" with regards to sex: Guide To Getting It On https://www.amazon.com/dp/B09QY4XC7Z/ I can't say for sure it "works", but I can say it has helped me get more comfortable with the topic.
If you want to talk or commiserate with, send me a DM.
El único libro que yo creo que puede cambiar la vida del 99% de las personas, especialmente latinos y gente que crecimos católicos, es "The Guide to Getting it On", de Paul Johannides. Tampoco es la primera vez que lo recomiendo.
