HELP<3

So I have blown this guy a couple of times that I used to date. I have never gone further and I feel like I'm not very good at it. I want to have fun enjoy myself and be confident but I just don't feel like I'm doing every thing right or it's not very good. Please please please give me advice on how I can be the best. I have read tips on here before but none of it has seemed to help.<3
