okay so here's how the story unfolds.

My boyfriend and I have been together for five months but known each other for a year. We are happy together and like anyone we also have our differences. We also have our moments in the bedroom.

Recently, my boyfriend mentioned that I don't feel the same every time we have sex, which means I have been with someone before or after him. I feel the same but different on some occasions, maybe the mood or stamina.

Main thing: I lost my virginity to him and I only been with him sexually. Also, I have been doing some exercises to keep downstairs from being "flappy". (TMI and sorry but I'm trying to make my point across that there's factors).

I didn't know how to take his comment and decided to ask and Google. Please help this curious topic and settle my case to him.
