Hornier than my boyfriend

Have been with my boyfriend officially nearly 3 months now and we’ve been having sex for maybe 5 months..the first time we had sex it was so good, lots of different positions and all.. now he’s just interested in normal missionary sex, no foreplay or anything, always leaves me horny. He does apologize for not being able to keep up with me but he’s very closed minded about foreplay and sex toys. He has no interest in exploring anything and it is quite frustrating. How do I get him to try new things?
