Please help with advice!!!

Hello! So my boyfriend and I have been having sex for a while now and he told me recently that I was the one to take his virginity. It completely shocked me since I had no clue and he never told me, but it happens. We both loved our first time so that’s what matters.

To the point now, he’s been wanting to expand our sexual relationship. I lost my virginity about two years ago, so I have a bit more experience than him. (He lost his this January.) He has told me he wants to go down on me and I am completely freaking out!!!

I have had others down there before without a problem, but I am so nervous for him to do it and whenever he offers I quickly come up with an excuse so he does not have to and I just end up giving him head. 😫😫😫

He also wants to finger me and I’m nervous for him to do that. He really really wants to do more for me, but I’m just nervous and I never tell him so he rubs me whenever I give him head.

I want to be more comfortable around him sexually but it is extremely difficult for me. I can’t even moan around him, granted I never moan during sex, just heavy breathing.

Is there anyway anyone could help or give me advice?

Feel free to ask any questions! :)
