Advice please

Okay so me and my boyfriend have known eachother for awhile, and we've been a thing for like four months and dating for one. And he's really shy, I took his virginity, but he also has a very out spoken personality, and I feel like we're fading apart, like we're too different. Because our views on everything are completely opposite. And we used to have sex like four times a day and now we barely even touch eachother anymore. Is this normal? Is he getting tired of me? Because were together every single day for three months now. And I don't know. Another thing is his friends bother me, like he won't hold my hand or want to kiss me in front of people, he's not even himself because he's scared theyll call him whipped. Idk what to do!! (He's 20 and I'm 17)
