If this decision or want of yours to do it is not fuelled by him pressuring you, or feeling obliged to do it cos you are in a relationship but srsly wanting to create that intimate connection with him or you just really want to experience it, then know that feeling nervous or awkward is normal if its your first time. The fear of the unknown is real and u just have to accept it or acknowledge it. But know that if you are 100% ready and have made up your mind, then take that leap babe. U never know. When the wanting overpowers the awkwardness and and nervousness, then take that leap.
Ps. Communicate with your partner on how u felt when u try to do it. So that he is aware of your condition. Maybe u both can find a middle ground between your nervousness and his eagerness.
Ps, if it helps u to feel better be sure to research ahead of the risks and preemptive/ protection measures, look for blogs. Or posts or comments that shares their first experiences cos they usually have a “if i did this” regret that wouldve made the experience better.
