I have 2 questions. I didnt bleed when i lost my virginity and have never bled during sex with that partner. However i have had sex with a different partner and i bled the first time with him. Does this mean my first partner did not break my hymen?

2nd question: during sex I get this feeling of needing to go for a number 2 making it difficult to enjoy. This usually happens if legs are lifted high in the air or doggy style (sorry about the details). After sex I let out a lot of gas which has odour not vaginal gas. I also feel very constituted for the whole day.
