tease too much 🤔

Soooo we having a good sex but, he comes so quickly 🙃 not that I complain but, he said that I tease him so much that he cums so shortly 😅 is there other way to make sex last longer? I feel I don't know much about sex, well I do but, like positions n stuff.. And maybe be more better in bed? 🤨 Again he tells be I'm really good in bed it's just that I'm teasing him much that he cums shortly 💭. I just feel a bit ridiculous in bed.. Because I don't know much about forplay and position since I haven't tried that much.. Even I really wanted too😅 and now I feel a bit embarrassed 🙃
