Anal sex need some information

This is embarrassing but i feel i need as many women's opinions as possible.

😭please don't laugh cos it's a fucking nightmare & very embarrassing for me to even admit this

im always very constipated because I have a hell of a lot of meds to take each day & my boyfriend says it's normal for couples to do anel sex i wanna try but I'm scared he knows i get constipated. Any advice on how best to go about trying this or should I say no no way.

Also i have some questions

1. Does it hurt as much as losing your virginity?

2. Can you bleed like you do when loesing your virginity?

3. Can you shit with anal sex🙈?

4. Can you have a orgasm from anel sex ?

5. What's the best position to try for a beginner?
