Beginner with lots of question

Short story:

So, im a virgin and all i have done have happened with this guy.

The time we have seen each other, he had all the pleasure and finish but I was like undone i didn’t had that much of excitement. After the last time he said he felt weird about what happened. We are not a couple but since then he is the one making first contact. So we are still talking but nothing has happen since that last time.

Questions:

Is it normal or has he developed some feeling or he is just telling nice things to be the first?

Is it normal to not get that exited the first time someone else touches you or that you feel more excitement when you do it yourself??

Im thinking of having sex for the first time with him (we both have the desired to do it). But I’m scare to not feel any excitement. How can I make sure both have pleasure?

Also if I do it a couple of days before my period start and use condom, is te risk of getting pregnant low almost zero?
