Sex with him

Alexis
My boyfriend and I have been off and on for three years and we had sex this last month for the first time. I was gone on vacation and when I got back it just kind of happened. The first time I was too tight and not wet enough so neither of us came and it was not enjoyable. A week or so later we had sex again, but no condoms. We had sex twice that night and three times total with no condom. I freaked out about getting pregnant because he came the night we had sex twice. Then we had sex a few days later with a condom and I had my period a few days later. So I know I'm not pregnant. But I haven't come once in the few times we've had sex. Is there something wrong with me??
