28 weeks... is painful sex normal ?

N

Throughout the pregnancy every time me and my partner had sex during and after it hurts really bad. We tried numerous things e.g lube, condoms and him ejaculating outside. I’ve been a voiding sex however I’ve been becoming more horny

Is it normal for it to hurt during and after (no orgasm for me) it also tends to burn however neither of us has any infections.

Should I discuss it with my midwife and if there anything else I can do for the meanwhile ?
