If I use a super absorbent tampon, will it rupture my cherry? Please reply because I'm thinking of using one as pads are uncomfortable when I workout

You decide. Remember that a tampon absorbs menstrual blood & will become thicker in the process. If you can slide it in without difficulty, it may have room to be extracted without pain/tearing. However, if it is a tight fit going in, expect problems getting it out.
Absorbency. Rupture of the hymen (cherry) can occur by many mechanisms, one of which may be insertion of a tampon, or commonly, exercise which impacts on the perineum. If you are concerned with being thought a virgin, there are gynecologists who will reconstruct a hymen if it has been previously ruptured. Go see someone and have this explained to you.
