hello! 20m here, i’ve been in a relationship with a plus sized woman for the past 6 months, and we have recently gotten intimate. i should mention i’m fairly new to sex and had my first time a few weeks ago. thing is, my girlfriend is plus-sized, and i’m pretty small compared to her. this makes it difficult to do stuff like missionary since her thighs are big, making it a challenge to fully get it in. we’ve had some success with missionary and i managed to get her off, but it’s still frustrating that i can’t get my full length in her, not to mention that i haven’t really gotten off through intercourse with her since it barely feels good for me. just looking to see if anybody here with more experience could lend me some advice.
