My boyfriend just left....but we both "did something" !!HELP?

Yeah, my boyfriend just left. And we've only been going out for 2 1/2 weeks. Randomly, (when we were making out) he started feeling up my shirt and getting rather "excited" shall I say. I let him feel me and stuff. But we both got carried away. VERY! Carried away....I wanted him to do it...but he fingered me...and i gave him head. i kinda feel bad now. Like Im afraid if someone finds out. And I feel good...because it felt good! And i kinda liked doing it to him. Also, is it normal for my to still be pounding and like a "vibration" in there...without a vibrator? And my mouth has this weird taste but i've been brushing my teeth for like the past 10 minutes!
