Hi everyone

I’m dating a nice guy who is a pro in sex. He always makes sure that I’m comfortable and I enjoy myself to the best. However, I don’t have as much experience as him. Sometimes I can’t even get him to an orgasm and I just get tired.I’ve talked to him about it and ask him what to do and he is always super nice about it. But I would love to get better. Is there anyway I can get the info about mens body and how to ride or give a blowjob or ...? Like good articles or tutorial videos?
