Is he still interested or do I have to regain his interest?

So I met this guy in the middle of April on a dating site. I hooked up with him and I thought I was just a one night stand but he still wanted to talk to me then we hooked up a second time at the end of April and I didn’t hear from him till the end of the week. Then during the summer he would be away for work because he’s in the Air Force and we spoke whenever it was possible to. When he came back I wanted to see him but he said he was kind of scared to see me because how good my vagina is which was a weird excuse to me. Sometimes he go days without responding to my text and I’m almost always the one to contact him. I understand he won’t always have time for me but I don’t know where we stand and I don’t want to ask him over text but I won’t be able to see him in person for a while.
