Frustrated with sex

Christina

I’m frustrated and could use any advice with sex. I’m new to it. I have a hard time relaxing the pelvic floor and the guy is always telling me to relax. How do I do that?

It was my first time doing cowgirl last night. I need more practice with that. Thighs become tired and finding a comfortable position to ride a hefty guy I need tips for that. Thank you so much!
