How do I know I'm not a virgin ?

I'm 17 years old I been with my boyfriend for 1 year I had sex with him for the first time last Friday we didn't use a condom he pulled out I didn't feel a thing and everytime we have sex I don't feel anything he enjoyed it more than me I want to enjoy it too. Is it me ? What should I do ? Am I a virgin ? How can I fix this ? I don't want to keep faking it I feel horrible I love him too much I want to experience the real thing with him
